The main reason for showing anomalous properties of the first member of a group in s or p-block is

A

Maximum chemical reactivity

B

Maximum electronrgativity and diferent configurations

C

Small size,'large charge/radius ratio

D

Tendency to form multiple bonds.

Text Solution

Verified by Experts

The correct Answer is:
C
Due to small size,large charge/radius ratio and high electronegativity,the first elements shows anomalous behavior.
