In chemistry , the valence or valency of an element is the measure of its combining capacity with other atoms when it forms chemical compounds or molecules. The combining capacity, or affinity of an atom of a given element is determined by the number of hydrogen atoms that it combines with. In methane , carbon has a valence of 4; in ammonia , nitrogen has a valence of 3; in water, oxygen has a valence of 2; and in hydrogen chloride, chlorine has a valence of 1. Chlorine, as it has a valence of one, can be substituted for hydrogen. Phosphorus has a valence of 5 in phosphorus pentachloride , PCl 5. Valence diagrams of a compound represent the connectivity of the elements, with lines drawn between two elements, sometimes called bonds, representing a saturated valency for each element. An alternative modern description is: [3].

John Dalton was the first to enunciate matter to be composed of invisible particles called atoms. Atoms means which cannot be cut uncut. So, an atom may be defined as the smallest particle of an element or chemical substance which generally participates in the chemical reaction but it may or may not have an independent existence. This means an atom is unstable. For example- Hydrogen gas is the smallest molecule which is composed of two atoms of hydrogen.

There are plenty of Positive and the Negative Radicals in the Chemistry. Some of the Important Positive and the Negative Radicals are written below. Radicals are the Positive and the Negative ions which have at least one unpaired electrons. Radicals or ions are formed by losing or gaining electrons. When an electron is gained the group of atoms acquire a negative charge and is called a negative radical or negative ion.

Valence (chemistry)

The term "valence" or "valency" is used in chemistry to describe the potential an element or molecule has to bond. Similar to oxidation number and formal charge of an ion, the valency of an atom or molecule can be described as how many hydrogen atoms it can bond with. Radicals are similar to polyatomic ions, only without a formal charge.

In chemistry , a radical is an atom , molecule , or ion that has an unpaired valence electron. Many radicals spontaneously dimerize. Most organic radicals have short lifetimes. Two other examples are triplet oxygen and triplet carbene : CH 2 which have two unpaired electrons.

Use the Octet Rule

Двухдюймовое искривленное стекло односторонней видимости открывало перед криптографами панораму зала, не позволяя увидеть камеру снаружи. В задней ее части располагались двенадцать терминалов, образуя совершенную окружность. Такая форма их размещения должна была способствовать интеллектуальному общению криптографов, напоминая им, что они всего лишь члены многочисленной команды - своего рода рыцари Круглого стола взломщиков кодов. По иронии судьбы в Третьем узле секреты не очень-то любили. Нареченный Детским манежем, Третий узел ничем не напоминал стерильную атмосферу остальной части шифровалки. Его обстановка напоминала домашнюю - мягкий ковер, высокотехнологичная звуковая система, холодильник, полный напитков и всяческой еды, маленькая кухня и даже баскетбольное кольцо. В отношении шифровалки в АНБ сложилась своеобразная философия.

 - Сколько. Беккер изобразил крайнюю степень негодования. - Вы хотите дать взятку представителю закона? - зарычал .

Что это за имя такое - Капля Росы. Он в последний раз взглянул на Клушара. - Капля Росы. Вы уверены.

Присяга, которую Чатрукьян принимал, поступая на службу в АНБ, стала непроизвольно прокручиваться в его голове. Он поклялся применять все свои знания, весь опыт, всю интуицию для защиты компьютеров агентства, стоивших не один миллион долларов. - Интуиция? - с вызовом проговорил. Не нужно интуиции, чтобы понять: никакая это не диагностика. Он решительно подошел к терминалу и запустил весь набор программ системных оценок ТРАНСТЕКСТА.
