choose the best classification.

element

compound

mixture of elements

mixture of compounds

mixture of elements and compounds

Explanation:

An element consists of only one type of atom. A compound has two or more different types of atoms chemically bonded. A mixture has different substances (elements or compounds) not chemically bonded. Here, all the molecules are the same (same combination of atoms), so it's a pure substance. Since there are different types of atoms in each molecule (as per the different - colored circles representing different atoms), it is a compound.

Compound
