7 A student was reading about the gases in air. Ozone helps protect Earth from harmful ultraviolet rays that come from the sun. Certain types of pollution created by humans have caused a hole in the ozone layer. This hole is over the South Pole and could become larger if this type of pollution increases.

GPT-4o mini · Answer

To determine if ozone is an elemental molecule, the student should ask:

C. What elements are present in the molecule?

An elemental molecule is composed of only one type of element, while ozone (O₃) consists of three oxygen atoms. So, understanding what elements make up the molecule is crucial to determine if it is an elemental molecule.
