Question

answer the questions in the table below about the shape of the ozone (o₃) molecule. how many electron groups are around the central oxygen atom? note: one \electron group\ means one lone pair, one single bond, one double bond, or one triple bond. what phrase best describes the arrangement of these electron groups around the central oxygen atom? (you may need to use the scrollbar to see all the choices.)

Explanation:

Step1: Analyze ozone structure

In the ozone ($O_3$) molecule, the central oxygen atom has 1 lone - pair of electrons and is bonded to 2 other oxygen atoms (one single bond and one double bond). So in total, there are 3 electron - groups around the central oxygen atom.

Step2: Determine electron - group arrangement

Based on VSEPR (Valence - Shell Electron - Pair Repulsion) theory, when there are 3 electron - groups around a central atom, the electron - group arrangement is trigonal planar.

Answer:

How many electron groups are around the central oxygen atom: 3
What phrase best describes the arrangement of these electron groups around the central oxygen atom: Trigonal planar
