Question

Conclusion of variable valency

Answer 1

Answer:

• Variable Valency. 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.
• Conclusion;
• An atom will always try to acquire an octet or acquire a state of stability by giving,taking or sharing electrons.The valency of an atom determines its combining capacity or the no. of electron it will gain,lose or share to become stable.
• For eg= chlorine's electronic configuration=2,8,7
• And it will gain 1 electron to become stable hence,its valency=1
