Q.
The total number of lone pairs of electrons in an $IF _{7}$ molecule is_____.
The p-Block Elements - Part2
Solution:
The structure of $IF _{7}$ is as follows:
There is no lone pair of electrons on central $I$ atom.
However, each of seven $F$ atoms contains $3$ lone pairs of electrons.
Hence, total number of lone pairs of electrons in an $IF _{7}$ molecule is $21$ .
