P-block elements

P-block elements. General electronic configuration of the groups are : ns 2 np 3 ,ns 2 np 4 , ns 2 np 5 , ns 2 np 6 . . Radii increase down the group, however down the group the increse is small due to filling of electrons in d and f shells.

Identify central atom and ligands

C, N, O, and F always obey octet rule . H, Be do not follow octet rule Example: BeCl 2 , H 2 . If only 3 electron groups around central atoms, then central atom forms incomplete octet Example: BH 3. Group III (13) elements such as B, Al . Identify central atom and ligands.
