Answer:

2 KCl

Explanation:

A has electronic configuration - 2,8,7.

It has 3 shells or orbits so it is placed in period 3.

It has 7 electrons in the outermost shell it is placed in group VII  A

B has electronic configuration - 2,8,8,1.

It Has 4 shells or orbits so it is placed in period 4

It Has 1 electron in its outermost shell so it is placed in group I A

A is Cl 1- And B is K 1+

2K + Cl ⇒ 2 KCl

           ²
