Question

why does sillver has a variable valency​

Answer 1

Answer:

Explanation:

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.

Answer 2

Answer:

Some elements show variable valency because of the different electronic configurations. Silver can sometimes lose more electrons than are present in its valence shell I.e. loss from the penultimate shell and hence exhibit than 1 or variable valency.
