Question

why silver has valency of +2 and +1

Answer 1

heyy ur answer.......


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.
