C
dioxygen
D
ozone
Verified step by step guidance1
Understand that oxygen can exist in different molecular forms, each with a specific number of oxygen atoms bonded together.
Recall that the most common form of oxygen we breathe is dioxygen, which consists of two oxygen atoms (O\_2) bonded together.
Recognize that when three oxygen atoms combine to form a molecule, this form is called ozone, represented chemically as O\_3.
Note that peroxide refers to compounds containing the O\_2\^{2-} ion, not a molecule of three oxygen atoms bonded together.
Therefore, the form of oxygen with three oxygen atoms per molecule is ozone.
