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. ..
Properties of compounds
. They have high melting point and even higher boiling points. The compounds belonging to group-II are either gases or liquids. They have very low melting and boiling points. One may wonder why this great variation exists in the properties of compounds? Examining the constituents of the c..
