Question

The atomic and ionic radii of sodium metal are
(A) 186 pm and 95 pm
(B) 95 pm and 95 pm
(C) 186 pm and 186 pm
(D) 95 pm and 186 pm​

Answer 1

The atomic and ionic radii of sodium metal are 186 pm and 95 pm

Therefore, option (A) is correct.

Explanation:

• The atomic radius of a cation will be greater than its ionic radius as it will be devoid of few electrons

• The Na atom in ionic form is Na⁺ which is without an electron

• Therefore, among the given options we need to choose the option where the atomic radius is greater than ionic radius

• In option (A), the atomic radius is greater than ionic radius

• Therefore from option (A), the atomic and ionic radii of sodium metal are 186 pm and 95 pm

Hope this answer is helpful.
