this chart shows four atoms, labeled w, x, y, and z. these atoms can combine with each other to form molecules.

which atoms could join together to form a molecule of an element?

w and x

x and y

w and z

y and z

Option (c) is the correct answer.

Explanation:

A molecule is defined as a substance which can contain atoms of same or different elements that are chemically combined together.

For example, , , etc are molecules.

Whereas a compound is defined as a chemical specie which is made by the combination of different atoms in a fixed ratio by mass.

For Example, , etc. are compounds.

A compound will also be considered as a molecule but a molecule can never be considered as a compound.

And, a molecule of an element will always contain atoms of one type of element.

As in the given situation both W and Z atoms represent the same element, that is, oxygen.

Thus, we can conclude that W and Z atoms could join together to form a molecule of an element.

the answer is d. 74.02
