B.) Substances that are made up of only one type of atom

Answer 2

Answer: substances that are made up of only one type of atom

Explanation:

Element is a pure substance which is composed of atoms of similar elements. Example: Carbon (C)

Compound is a pure substance which is made from atoms of different elements combined together in a fixed ratio by mass. Example: water

The subatomic particles with a positive charge are called as protons and are located in the nucleus of the atom.

Thus elements are substances that are made up of only one type of atom.
