Question

defined the hybridisation ? what is the hybridization of IF7

Answer 1

Hybridization happens when atomic orbital mix to form a new atomic orbital. The new orbital can hold the same total number of electron as the old ones. The properties and energy of the new, hybridized orbital are an 'average' of the original unhybridized orbitals.
The concept of hybridization was introduced because it was the best explanation for the fact that all the C - H bonds in molecules like methane are identical.

❣❣HERE IS YOUR ANSWER ❣❣
$Hybridization:-$
____________________________________
Hybridization means intermixing of one or two different or same atomic orbitals to form some energy level new or hybrid orbitals form is called hybridization.
In other word, mixing of a atomic orbital to form molecular orbitals.
Hybridization of IF7 = sp^3d^3.
