How do modern scientist describe the make up of matter

The matter is a collection or composition of extremely small particles called "Atoms".

Explanation:

The matter is anything that has mass and which utilizes space by having volume. Modern scientists describe the makeup of matter as a collection of tiny substances called atoms. Matter can either be in solid, liquid, or gaseous state and even appear in plasma form. Matter can neither be created nor be destroyed but only transferred from one form to the other. Atoms are composed protons, neutrons and electrons. The protons and neutrons are contained in the nucleus, while the electrons orbit around the nucleus of the atom. Protons are positively charged, neutrons are neutral and electrons are negative.
