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
