Question
The expanded octet
Elements in and beyond the third period of
the periodic table have, apart from 3s and 3p
orbitals, 3d orbitals also available for bonding.
In a number of compounds of these elements
there are more than eight valence electrons
around the central atom. This is termed as
the expanded octet. Obviously the octet rule
does not apply in such cases.
Some of the examples of such compounds
are: PF). SF, H,50, and a number of
coordination compounds.
