Question

Why silver exhibits a valency of +1 & +2

Answer 1

This property is called as variable valency. Some elements show variable valency because of the different electronic configurations. An atom of an element can sometimes lose more electrons than are present in its valence shell i.e. loss from the penultimate shell and hence exhibit more than 1 or variable valency.

Answer 2

Ag(SILVER) LIES IN the group of Transition elements(d-block elements) and d-block elements exhibit variable valency and oxidation state....
