Question

Why metallic bonds are non-directional?

(a) Because there is a uniform distribution of mobile valence electrons around the kernels

(b) Because there is a non-uniform distribution of mobile valence electrons around the kernels

(c) There is no change in inter-kernel distance

(d) There is a change in inter-kernel distance

The question was posed to me in an international level competition.

Answer 1

Correct answer is (a) Because there is a uniform distribution of mobile valence electrons around the kernels

For explanation: Metallic bonds are non-directional because there is a uniform distribution of mobile valence electrons around the kernels, provided there is no change in inter-kernel distance.
