Answers

Answered by apurva4335

Answer:

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.

Answered by shreyoyakkha2005

Answer:Because some elements loose,gain or share to attain the nearest noble gas configuration. Thus certain elements show positive valence whereas certain show negative valence.
