NEET UG CHEMISTRY MCQ: CHEMICAL BONDING & MOLECULAR STRUCTURE

The electronic configuration of four elements are as follows.

$a : 1 {s}^2 2 {s}^2 2 {p}^4$

$b : 1 {s}^2 2 {s}^2 2 {p}^5$

$c : 1 {s}^2 2 {s}^2 2{p}^6 3 {s}^1$

$d: 1 s^2 2 s^2 2 p^6 3 s^2$

Now decide the possible formulae of ionic compounds that could be formed between them.
