Question

Atomic number of metal A is "11".while atomic number of metal "B" is 20 .which of them will be more reactive? write the Chemical reactive of dilute kcl with metal "A".​

Answer 1

OKK

Explanation:

Atomic number of A is 11 so electronic configuration of Ais 2,8,1

Atomic number of B 20,50 Electronic configuration of B is 2,8,8,2

Metal A is more reactive because it has only one balence electron to lose and it will lose it readily.

Reaction

A + HCIV--> ACI + H
