Question

The electronic configurations of two elements A and B are given below:

A 2, 6
B 2, 8, 1

(a) What type of chemical bond is formed between the two atoms of A?
(b) What type of chemical bond will be formed between the atoms of A and B?

Solution

(a) Two atoms of A can form covalent bond between them by sharing two electrons from each atom. This allows them to complete their octets and get stabilised. The molecule so formed is A=A.
(b) Atoms A and B may react to form ionic bond by transfer of two electrons from two atoms of B to form an ionic compound AB2.

  Is there an error in this question or solution?
