C., it was believed that all matter was made up of four elements including earth, fire, air and water. At around this time, Democritus proposed the idea of matter being made up of small indivisible particles. He called these particles atomos, or atoms. Click to see full answer.

• It depends on which matter you are considering. If you are thinking about the everyday stuff, things like trees, mountains, people, air, etc, then yes, these are all made of atoms (or ionized atoms).
• This chapter explains how matter is built from a handful of tiny “bricks” called fundamental particles. Although twelve different bricks have been found, only three are needed to form all atoms found on Earth, in stars and in galaxies.

What is an atom? What are atoms made of?

Atoms are the basic building blocks of ordinary matter. Atoms can join together to form molecules, which in turn form most of the objects around you.

Atoms are composed of particles called protons, electrons and neutrons. Protons carry a positive electrical charge, electrons carry a negative electrical charge and neutrons carry no electrical charge at all. The protons and neutrons cluster together in the central part of the atom, called the nucleus, and the electrons 'orbit' the nucleus. A particular atom will have the same number of protons and electrons and most atoms have at least as many neutrons as protons.

Protons and neutrons are both composed of other particles called quarks and gluons. Protons contain two 'up' quarks and one 'down' quark while neutrons contain one 'up' quark and two 'down' quarks. The gluons are responsible for binding the quarks to one another.
