Question

Why does silver show variable valency?

Answer 1

Hey mate here we go

Some elements show variable valency because of the different electronic configurations.
Ex:Silver 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.

I hope this will helps you

mark my ans as brainliest

Answer 2

hey mate here is your answer:

some elements show different or variable valency due to their different electronic confiriguration.

silver can lose more electrons than that are present in its valence shell and hence exhibit more than 1 or variable valency.

I hope this helps you..
