What is the total number of lone pairs of electrons present on the central iodine atom in a molecule — p Block Elements Chemistry Question

💡 Solution & Explanation

Iodine has 7 valence electrons. In $IF_7$, it forms 7 single bonds with 7 fluorine atoms. All 7 valence electrons are involved in bonding, leaving 0 lone pairs on the central iodine atom. The hybridization is $sp^3d^3$ (pentagonal bipyramidal).
