Answer 2

Perodicity of Element

The property that reappear at regular intervals and there is gradual variation at a regular interval is called Periodicity property .

________________________________

What can be the causes of Periodicity:-

• It can be caused by recurrence of similar electronic configuration .
• They have same number of electrons in the outermost orbit.
• The chemical property of electrons depends upon the number of electrons in the outermost shell does element of same group have similar property .

1. Valency -Valency is the combining capacity of an atom heat is equal to number of electrons and atom can donate or accept or share .
2. metallic character those elements which have tendency to lose the valence electron and form a positive ions . These known as metallic character of the element .
