Question

What are the relatioships between group configuration and group number for elements in the s, p and d blocks?

Answer 1

Answer:

Explanation:

For s block valence electronic configuration is ns 1 to 2.

And thus group no = no of valence electron (i.e. electrons in ns ).

For d block valence electronic configuration is (n-1)d 0 to 10 ns 0 to 2.

And gp. no= no of valence electron (i.e. electrons in (n-1) d and ns).

For p block valence electronic configuration is ns 2 np 0 to 6.

And gp. No= 10+ no of valence electron (i.e. electrons in ns and np)
