Each cell of the IPTEI provides the chemical name, symbol, atomic number, and standard atomic weight of an element. Color-coded pie charts in each element cell display the stable isotopes and the relatively long-lived radioactive isotopes having characteristic terrestrial isotopic compositions that determine the standard atomic weight of each element. The background color scheme of cells categorizes the elements into four groups: 1 white indicates the element has no standard atomic weight, 2 blue indicates the element has only one isotope that is used to determine its standard atomic weight, which is given as a single value with an uncertainty, 3 yellow indicates the element has two or more isotopes that are used to determine its standard atomic weight, which is given as a single value with an uncertainty, and 4 pink indicates the element has a well-documented variation in its atomic weight, and the standard atomic weight is expressed as an interval.

She has taught science courses at the high school, college, and graduate levels. Thus, according to this method, 2 electrons are allotted in the first shell, 8 electrons in the second shell, and 18 electrons in the third shell.

Chemistry is the science of substances, their properties, structure and transformations that result from chemical reactions, as well as the laws that govern these transformations.

All substances are composed of atoms, which are capable of forming molecules due to their chemical bonds. Chemistry mainly deals with these interactions at the atomic-molecular level, that is, at the level of chemical elements and their compounds.

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

The system is a graphic representation of the periodic law established by the Russian chemist Dmitri Mendeleev in Its initial version was developed by Dmitri Mendeleev in and established that the properties of elements depended on their atomic mass. The periodic table in your smartphone that is always with you in your pocket will help you quickly learn all the necessary information about the chemical elements and use it in an exam, in a laboratory, or just in a chemistry lesson.

The periodic table is suitable for both schoolchildren who are just starting to study chemistry, and students of chemical departments or specialists in the chemical industry.

In this form, the table consists of 18 groups and currently presents chemical elements. Besides, an animated diagram of electronic shells is displayed for each element. The application has a convenient search tool that helps you quickly find a particular element by symbol, name or atomic number. In addition to all of the above, the paid package contains such interesting things as: 1.

A photo of an element that shows what a particular chemical element looks like in reality or in laboratory conditions. A list of isotopes of elements and their respective properties. An isotope is an atom of a chemical element that differs from another atom of the same element by its atomic weight.

The solubility table of salts, acids and bases, which is essential for studying chemistry, especially at school. Solubility is the ability of a substance to form homogeneous systems with other substances - solutions in which the substance stays in the form of individual atoms, ions, molecules or particles.

The solubility table is used to verify the reaction conditions. Since the formation of a precipitate irreversibility of the reaction is one of the prerequisites of the reaction, the solubility table will help you check whether a precipitate is formed and thereby determine whether the reaction occurs or not.

Here's a list of the chemical elements ordered by increasing atomic number. The names and element symbols are provided. Each element has a one- or two-letter symbol, which is an abbreviated form of its present or former name. The element number is its atomic number, which is the number of protons in each of its atoms. Most elements on the periodic table are metals and have the -ium suffix. Halogen names usually end with -ine.

A List of the Elements of the Periodic Table

In chemistry , an element is a pure substance consisting only of atoms that all have the same numbers of protons in their atomic nuclei. Unlike chemical compounds , chemical elements cannot be broken down into simpler substances by chemical means. The number of protons in the nucleus is the defining property of an element, and is referred to as its atomic number represented by the symbol Z — all atoms with the same atomic number are atoms of the same element.

Oganesson is a synthetic chemical element with the symbol Og and atomic number It was formally named on 28 November It is one of only two elements named after a person who was alive at the time of naming, the other being seaborgium , and the only element whose namesake is alive today. Oganesson has the highest atomic number and highest atomic mass of all known elements. The radioactive oganesson atom is very unstable, and since , only five possibly six atoms of the isotope oganesson have been detected.

1 Introduction

По другой стороне улицы, оставаясь невидимым, шел человек в очках в тонкой металлической оправе. ГЛАВА 27 Тени в зале шифровалки начали удлиняться и терять четкость. Автоматическое освещение постепенно становилось ярче. Сьюзан по-прежнему молча сидела за компьютером, ожидая вестей от Следопыта. Поиск занял больше времени, чем она рассчитывала. Мысли ее мешались: она тосковала по Дэвиду и страстно желала, чтобы Грег Хейл отправился домой. Но Хейл сидел на месте и помалкивал, поглощенный своим занятием.

ME TOO, что означало: Я. Беккер расхохотался. Он дожил до тридцати пяти лет, а сердце у него прыгало, как у влюбленного мальчишки. Никогда еще его не влекло ни к одной женщине. Изящные европейские черты лица и карие глаза делали Сьюзан похожей на модель, рекламирующую косметику Эсте Лаудер. Худоба и неловкость подростка бесследно исчезли.

Ничего страшного - это глупая болтовня. То, что там происходит, серьезно, очень серьезно.

Кто будет охранять охранников. - Вот. Если мы - охранники общества, то кто будет следить за нами, чтобы мы не стали угрозой обществу. Сьюзан покачала головой, не зная, что на это возразить. Хейл улыбнулся: - Так заканчивал Танкадо все свои письма ко .

 - Мне необходимо решение. Или мы начинаем отключение, или же мы никогда этого не сделаем. Как только эти два агрессора увидят, что Бастион пал, они издадут боевой клич.

 Утечка информации! - кричал кто-то.  - Стремительная. Все люди на подиуме потянулись к терминалу в одно и то же мгновение, образовав единое сплетение вытянутых рук. Но Сьюзан, опередив всех, прикоснулась к клавиатуре и нажала цифру 3. Все повернулись к экрану, где над всем этим хаосом появилась надпись: ВВЕСТИ ПАРОЛЬ.

Когда он поднес раскаленный конец паяльника к последнему контакту, раздался резкий звонок мобильного телефона. Джабба вздрогнул, и на руку ему упала шипящая капля жидкого олова. - Черт возьми! - Он отшвырнул паяльник и едва не подавился портативным фонариком.
