Question

Out of the following, which one is a correct statement :

• A. Ionic radius of a metal is same as its atomic radius
• B. The ionic radius of a metal is less than its atomic radius
• C. The ionic radius of a metal greater than its atomic radius
• D. The atomic radius of a non-metal is more than its ionic radius

Answer 1

The correct option is B The ionic radius of a metal is less than its atomic radius

Metals are electropositive in nature i.e., loose $e^{–}$, therefore its ionic radius will be less than the atomic radius i.e, nuclear charge per electron decreases.
