Question

identify each of the images as an element, molecule or compound.

Explanation:

An element consists of only one - type of atom. A molecule is a group of two or more atoms held together by chemical bonds. A compound is a substance made up of two or more different types of elements chemically combined. In image A, there are single - type atoms, so it's an element. In image B, there are groups of the same type of atoms (diatomic molecules), so it's a molecule of an element. In image C, there are groups of different types of atoms chemically combined, so it's a compound.

Answer:

A. element
B. molecule
C. compound
