What is the steric number with respect to the central carbon atom in the Lewis structure for carbon dioxide, CO₂?

Question

Quizplus · Accepted Answer

The steric number is determined by the sum of the number of atoms bonded to the central atom and the number of lone pair electrons on it. In carbon dioxide (CO2), the central carbon atom is double bonded to two oxygen atoms and has no lone pairs, giving it a steric number of 2.
