Question

question 10 (1 point) saved a molecule exhibits the trigonal planar shape. how many electron groups exist in the valence shell for the central atom in this molecule? two three four five

Explanation:

Step1: Recall VSEPR theory

In VSEPR (Valence - Shell Electron - Pair Repulsion) theory, a trigonal planar molecular shape has 3 electron - groups around the central atom. These electron - groups can be bonding pairs or lone pairs.

Answer:

Three
