Why do elements in the same period have ...

Why do elements in the same period have different physical and chemical properties? What about elements in the same group?

Text Solution

Verified by Experts

Elements in the same period have the same outermost shell for different outermost electronic configuration and hence have different physical and chemical properties. However, elements in the same group have similar outermost electronic configuration have similar physical and chemical properties.
