Question

Decribe the theory associated with the radius of an atom as it-

(a) Gain on electron.

(b) Loses on electron.​

Answer 1

Answer:

when an atom gains an electron to form anion ,its radius increases . ... when an atom loses an electron to form cation , its radius decreases . due to decreases number of electrons , nuclear charge per electron is increases , hence, effective nuclear charge increases as a result radius of cation decreases.
