What types of matter are made of atoms?

All matter is made of atoms

All things which are considered as matter are composed of atom.

Anything which has mass and volume to occupy space is called as matter. The fundamental unit of matter is known as atom which is in turn composed of three notable particles called protons, neutrons, and electrons. All the substance which exists on earth is called as matter and they are classified as solid, liquid, gas and newly identified plasma.

Thus, it can be inferred that all the types of matter which includes solid, liquid, gas and plasma are composed of atom.
