What is the steric number with respect to the central iodine atom in the Lewis structure for the species, ICl₂^{1 -}?

Question

Quizplus · Accepted Answer

The steric number is determined by adding the number of bonded atoms to the central atom and the number of lone pairs on the central atom. In the given species, ICl₂^{1 -}, the central iodine atom is bonded to one chlorine atom and has three lone pairs, giving a steric number of 4 (1 bond + 3 lone pairs).
