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.

Element Valency PDF

In a chemical reaction, the molecular composition changes and it is represented by a chemical equation. In a chemical equation, the various substances involved as reactants or products are written in the form of symbols and formulae. Symbol of an Element:. A symbol is a representation of an atom of an element. These are unique 1,2, and 3 letter symbols. The first letter of an Element symbol is always a capital letter and remaining letters are written in lower case only. Many of the element symbols reflect the English name of the element such as Oxygen O , hydrogen H , carbon C , nitrogen.

Radical (chemistry)

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.

Valence (chemistry)

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.

The term "valence" or "valency" is used in chemistry to describe the potential an element or molecule has to bond.
