Sodium belongs to Group I in the periodic table. This group is otherwise known as the alkali metals group. Since the atomic number of sodium is 11, its electronic configuration is 2,8,1. Sodium easily loses the lone electron to attain the stable configuration of neon. Therefore alkali metals ..

The reactivity of metals decreases from left to right in a period while the reactivity increases down the group. The reactivity of non-metals increases from left to right in a period while the reactivity decreases down the grou..

The halogens are the most reactive elements as a family. Fluorine is the most reactive of all the halogens. The reactivity of the halogens decreases down the grou..

Every chemical substance is known by a specific name. But many a times these names are cumbersome, confusing, and do not provide information about its chemical composition. To overcome this, each chemical compound is represented by a chemical f..

Introduction - Let us examine closely the following sets of compounds and study their properties in terms of their physical state, melting points and boiling point..

Combination of Elements - Atoms of elements combine to form molecules of compounds. This combination can occur in two ways: either by electrovalent bonding or covalent bonding. In all chemical reactions it is the electrons from the outermost shell of an atom that are involved in..
