Question

What is the relationship between the group number of the representative elements and the number of valence electrons?

Answer 1

Answer:

Explanation:

For s block element---:

Group no. = no of valence electron

For p block element----:

Group no. = 10+ no of valence electron {i.e. electron in ns and np }

For d block element---:

Group no. = no of valence electron {no of electron in (n-1)d + ns }
