Question

the variable velancy of element iron is​

Answer 1

Answer:

For example, iron combines with oxygen to form ferrous oxide as well as ferric oxide. In the formation of ferrous oxide, iron exhibits a valency of +2, whereas in ferric oxide, it has a valency of +3. This is termed variable valency.

The valence is known as an element's combining power. Some elements vary in their ability to interact with other elements, depending on the nature of the reaction; variable valence is called this property. Iron (Fe), for example, may h

Answer 2
