Why do some elements show variable valency?
Asked by | 23rd Oct, 2013, 10:44: PM
Sometimes, same element may exhibit one valency in one compound and another valency in other compound. 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.
