Give the meaning of following:

${\mathrm{Na}}^{+}$

Answer 1

Radical:

• Most inorganic compounds are made up of two oppositely charged parts called radicals.
• A radical is defined as an atom or a group of atoms that carries a positive or negative charge and behaves as a single unit in a chemical reaction.
• For example, ${\mathrm{Na}}^{+},{\mathrm{Cl}}^{-},{\mathrm{S}}^{2-},\mathrm{etc}.$

${\mathrm{Na}}^{+}$ is a cation or basic radical.

Basic radical:

• The positively charged part is called cation or basic radical or electropositive radical.
