Question

How are the element with Variable valency Named?Explain wi
th an example

Answer 1

Answer:

For example, the valency of Hydrogen is 1 as it has one electron in its outermost shell and requires one electron to become stable. Some elements differ in their capacity to combine with other elements depending on the nature of the reaction; this property is called variable valency.

Answer 2

Answer:

Certain elements combine with other atoms, donating, accepting or sharing electrons in different proportions depending on the nature of the reaction. For example, iron combines with oxygen to form ferrous oxide as well as ferric oxide. This is termed variable valency. ...

Variable valency : d-block elements show variable valency because electrons present in ns and (n-1)d take part in bond formation . 3) Metallic nature : All d-block elements are metals.
