Introduction

There is science in the world, without which today it is impossible to realize the most fantastic projects and fabulous dreams. This is CHEMISTRY. She feeds, waters, clothes, heals, washes, extracts minerals, allows you to rise into space and sink to the bottom of the ocean.

One of the greatest scientific discoveries XIX century in the field of chemistry, the Periodic Law and the Periodic Table of Chemical Elements, which bear the name of the great Russian scientist D.I., are rightfully considered. Mendeleev (this year he celebrated his 110th birthday).

The periodic system of chemical elements (Mendeleev's table) is a classification of chemical elements that establishes the dependence of various properties of elements on the charge of the atomic nucleus.

To assist students in studying the topic “Periodic Law and the Periodic System of Chemical Elements by D. I. Mendeleev,” I have developed my own educational product, “Interactive Periodic Table,” whichruns on its own engine.

The purpose of this work:create a simple and user-interesting dynamic model of the Periodic Table.
Tasks:
broaden your horizons in the field of chemistry of elements;
deepen knowledge of chemistry;
develop skills in creating websites and working with various information applications.

Chapter 1. Structure of the periodic table D.I. Mendeleev

The original version of the table was developed by D.I. Mendeleev in 1869–1871 and included 63 elements. Over the past 50 years, 17 new elements have been added to the periodic table of Mendeleev (serial numbers 102-118).

In November 2016 The International Union of Pure and Applied Chemistry announced the official addition of four new chemical elements to the periodic table. The new elements are numbered 113, 115, 117 and 118.

The element with serial number 113 received the name “nihonium”, from the Japanese scientists who discovered it, which is translated into Russian as “Land of the Rising Sun”.

The 115th element was named “Moscow” in honor of the Moscow region, where the Joint Institute for Nuclear Research in Dubna is located.

Element 117 was added to the table under the name "tennessine" (the name was proposed by specialists from the National Laboratory of Tennessee, USA, who made a great contribution to the study of superheavy chemical elements) and number 118 - "oganesson" (named after the academician of the Russian Academy of Sciences, scientific director of the Laboratory of Nuclear Reactions of the JINR Yuri Oganesyan).

This program has an intuitive interface with which any user can obtain the necessary information (description; obtaining; application; occurrence in nature; biological role) about each chemical element of the periodic table by selecting the desired element.

The program includes an interactive game "Periodic Table", which can be used as a simulator to test knowledge of chemical elements. To run the simulator, you must connect your computer to the Internet.

The game offers you to find chemical elements using different options: their name, designation, atomic mass. You can search according to the option that is convenient for you, by selecting, for example, the simplest elements, the top of the table, or the entire table. The game can be made more difficult by setting a timer. You can also remove the names or symbols of chemical elements. In general, try it! Game taken onhttp://www.xumuk.ru/ .

To manifest your intellectual abilities, demonstration of acquired knowledge and logical thinking in the field of chemistry, the program includes an intellectual game “Tournament of Chemistry Experts”, which can be used to test knowledge

The program includes information about the history of the creation of the D.I. table. Mendeleev, its structure and the significance of the periodic system for science.

The program also contains information about the authors and links to Internet sources.

Chapter 2. Stages of writing a software product

The main stages that were completed when writing a software product:

Visual programming stage.
Source code programming stage.
Checking the functionality of the program.

The program does not require installation and is small in size. Despite its small size, it has the functionality of its much larger counterparts. An executable (*.exe) file, which is automatically specified during program compilation, is a completely independent application.

To run the program, you need to double-click on the permission file (Table.exe), after which the program window will appear on the screen, which has a convenient, attractive user interface.

This electronic publication can be used in various ways depending on the equipment of the office:

This program is a short reference guide to the periodic table of chemical elements.

The program contains information about each element:

Description of the chemical element;

Methods of obtaining;

Areas of use;

Being in nature;

Biological role.

The interactive game "Periodic Table", which is included in this program, can be used as a simulator to test knowledge of chemical elements.

The intellectual game “Tournament of Chemistry Experts” can be used to test knowledgestudents on the topic “Periodic law and the periodic system of chemical elements of D.I. Mendeleev” in a playful way.

Using the interactive periodic system, you can easily and quickly find information about the history of the creation of the D.I. table. Mendeleev, its structure and the significance of the periodic system for science and prepare additional material for chemistry classes.

This educational product can be useful to students who will find interesting information about chemical elements, as well as to chemistry teachers to improve the quality of education in the discipline.
During the work on this project, the following tasks were solved:
knowledge of chemistry has been deepened;

The horizons in the field of chemistry of elements have been expanded;
skills in creating websites and working with various information applications have been developed.

Since all the objectives of the research project were solved, it can be argued that the goal “create a simple and user-interesting dynamic model of the Periodic Table” has been achieved.

The periodic table is one of greatest discoveries humanity, which made it possible to organize knowledge about the world around us and discover new chemical elements. It is necessary for schoolchildren, as well as for anyone interested in chemistry. In addition, this scheme is indispensable in other areas of science.

This scheme contains all the elements known to man, and they are grouped depending on atomic mass and atomic number. These characteristics affect the properties of the elements. In total, there are 8 groups in the short version of the table; the elements included in one group have very similar properties. The first group contains hydrogen, lithium, potassium, copper, whose Latin pronunciation in Russian is cuprum. And also argentum - silver, cesium, gold - aurum and francium. The second group contains beryllium, magnesium, calcium, zinc, followed by strontium, cadmium, barium, and the group ends with mercury and radium.

The third group includes boron, aluminum, scandium, gallium, followed by yttrium, indium, lanthanum, and the group ends with thallium and actinium. The fourth group begins with carbon, silicon, titanium, continues with germanium, zirconium, tin and ends with hafnium, lead and rutherfordium. The fifth group contains elements such as nitrogen, phosphorus, vanadium, below are arsenic, niobium, antimony, then comes tantalum, bismuth and completes the group with dubnium. The sixth begins with oxygen, followed by sulfur, chromium, selenium, then molybdenum, tellurium, then tungsten, polonium and seaborgium.

In the seventh group, the first element is fluorine, followed by chlorine, manganese, bromine, technetium, followed by iodine, then rhenium, astatine and bohrium. The last group is the most numerous. It includes gases such as helium, neon, argon, krypton, xenon and radon. This group also includes metals iron, cobalt, nickel, rhodium, palladium, ruthenium, osmium, iridium, and platinum. Next come hannium and meitnerium. The elements that form the actinide series and lanthanide series. They have similar properties to lanthanum and actinium.

This scheme includes all types of elements, which are divided into 2 large groups - metals and non-metals, having different properties. How to determine whether an element belongs to one group or another will be helped by a conventional line that must be drawn from boron to astatine. It should be remembered that such a line can only be drawn in full version tables. All elements that are above this line and are located in the main subgroups are considered non-metals. And those below, in the main subgroups, are metals. Metals are also substances found in side subgroups. There are special pictures and photos in which you can familiarize yourself in detail with the position of these elements. It is worth noting that those elements that are on this line exhibit the same properties of both metals and non-metals.

A separate list is made up of amphoteric elements, which have dual properties and can form 2 types of compounds as a result of reactions. At the same time, they manifest both basic and acid properties. The predominance of certain properties depends on the reaction conditions and substances with which the amphoteric element reacts.

It is worth noting that this scheme, in its traditional design of good quality, is colored. At the same time, for ease of orientation, they are indicated in different colors. main and secondary subgroups. Elements are also grouped depending on the similarity of their properties.
However, nowadays, along with the color scheme, the black and white periodic table of Mendeleev is very common. This type is used for black and white printing. Despite its apparent complexity, working with it is just as convenient if you take into account some of the nuances. So, in this case, you can distinguish the main subgroup from the secondary one by differences in shades that are clearly visible. In addition, in the color version, elements with the presence of electrons on different layers are indicated different colors.
It is worth noting that in a single-color design it is not very difficult to navigate the scheme. For this purpose, the information indicated in each individual cell of the element will be sufficient.

The Unified State Exam today is the main type of test at the end of school, which means that special attention must be paid to preparing for it. Therefore, when choosing final exam in chemistry, you need to pay attention to materials that can help you pass it. As a rule, schoolchildren are allowed to use some tables during the exam, in particular, the periodic table in good quality. Therefore, in order for it to bring only benefits during testing, attention should be paid in advance to its structure and the study of the properties of the elements, as well as their sequence. You also need to learn use the black and white version of the table so as not to encounter some difficulties in the exam.

In addition to the main table characterizing the properties of elements and their dependence on atomic mass, there are other diagrams that can help in the study of chemistry. For example, there are tables of solubility and electronegativity of substances. The first can be used to determine how soluble a particular compound is in water at normal temperature. In this case, anions are located horizontally - negatively charged ions, and cations - that is, positively charged ions - are located vertically. To find out degree of solubility of one or another compound, it is necessary to find its components using the table. And at the place of their intersection there will be the necessary designation.

If it is the letter “p”, then the substance is completely soluble in water under normal conditions. If the letter “m” is present, the substance is slightly soluble, and if the letter “n” is present, it is almost insoluble. If there is a “+” sign, the compound does not form a precipitate and reacts with the solvent without residue. If a "-" sign is present, it means that such a substance does not exist. Sometimes you can also see the “?” sign in the table, then this means that the degree of solubility of this compound is not known for certain. Electronegativity of elements can vary from 1 to 8; there is also a special table to determine this parameter.

Another useful table is the metal activity series. All metals are located in it according to increasing degrees of electrochemical potential. The series of metal voltages begins with lithium and ends with gold. It is believed that the further to the left a metal occupies a place in a given row, the more active it is in chemical reactions. Thus, the most active metal Lithium is considered an alkaline metal. The list of elements also contains hydrogen towards the end. It is believed that the metals located after it are practically inactive. These include elements such as copper, mercury, silver, platinum and gold.

Periodic table pictures in good quality

This scheme is one of the largest achievements in the field of chemistry. Wherein there are many types of this table– short version, long, as well as extra-long. The most common is the short table, but the long version of the diagram is also common. It is worth noting that the short version of the circuit is not currently recommended for use by IUPAC.
In total there were More than a hundred types of tables have been developed, differing in presentation, form and graphical representation. They are used in different fields of science, or are not used at all. Currently, new circuit configurations continue to be developed by researchers. The main option is either a short or long circuit in excellent quality.

Dmitry Ivanovich Mendeleev dreamed of a table of chemical elements in the mid-19th century. It’s true that it was a dream, or it’s just a beautiful legend, but students and scientists still use the periodic table, it turned out to be such a convenient reference book. The program, which is called “D.I. Mendeleev’s Periodic Table of Elements,” is a free electronic reference book containing the periodic table of chemical elements, detailed information about each element, as well as the theory of development of the periodic table of chemical elements.

Periodic table

The program is easy to use, just hover your mouse over a chemical element in the periodic table to get detailed information about it:

element name in Russian, German, English, French, Spanish and Latin;
electronic structure;
serial number in the table of chemical elements;
group;
period;
atomic mass;
electronegativity;
density;
atomic radius;
atomic volume;
covalent radius;
element content in the earth's crust;
characteristic oxidation states;
melting and boiling points;
first and second ionization potentials;
color of a chemical element;
opened by whom, when and in what country.

The program has a nice interface, transparency and image quality can be adjusted. The application can be run in full screen mode, and when combined with a projector, it produces a beautiful, visual, and interactive reference guide that can be used for educational purposes. The periodic table does not require preliminary installation; you can write the program onto a flash drive so that it is always at hand.
