Why do elements with similar properties occur in the same group?

Text Solution

Verified by Experts

The physical and chemical properties of elements depend on the number of valence electrons. Elements present in the same group have the same number of valence electrons. Therefore, elements present in the same group have similar physical and chemical properties.
