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: Draw ozone Lewis structure

The ozone ($O_3$) molecule has a central oxygen atom bonded to two other oxygen atoms. The central oxygen has one double - bond, one single - bond and one lone - pair of electrons. So the number of electron groups around the central oxygen atom is 3.

Step2: Determine electron - group arrangement

According to the 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
