Answer»

Question 14

The electronic configurations of the elements A, B and C are given below. Answer the question on the basis of these configurations.

A $1 s^{2}$ $2 s^{2}$ $2 p^{6}$

B $1 s^{2}$ $2 s^{2}$ $2 p^{6}$ $3 s^{2}$ $3 p^{3}$

C $1 s^{2}$ $2 p^{6}$ $2 p^{6}$ $3 s^{2}$ $3 p^{5}$

Stable form of A may be represented by the formula

(a) A

(b) $A_{2}$

(d) $A_{4}$
