Question

Define atomic radius of an atom and explain how it differs from anionic and cationic radius.

Answer 1

Explanation:

Atomic radius is refers to atomic size of an atom.

The atomic size may be visualised as the distance b/w the centre of the nucleus and the outermost shell of an isolated atom . The atomic radius decreases in moving from left to right in a period due to an increase in nuclear charge which trends to pull the electrons closer and in group up to down increases due split of nuclear charge
