The central iodine atom in IF₅ has __________ unbonded electron pairs and __________ bonded electron pairs in its valence shell.

Question

Quizplus · Accepted Answer

Iodine belongs to group 7A or 17 in the periodic table and has 7 valence electrons. In IF₅, there are 5 bonded atoms to the central iodine atom, which means that there are already 5 pairs of electrons involved in covalent bonding. Moreover, in order to satisfy the octet rule, iodine needs one more electron pair. Therefore, it has only one unbonded electron pair.

The Central Iodine Atom in IF5 Has __________ Unbonded Electron

The Central Iodine Atom in IF₅ Has __________ Unbonded Electron
