No one really knows everything is made out of atoms Scientists create models to describe them.
Scientists describe atoms as the basic building blocks of matter that make up everything in the universe. Atoms are composed of a nucleus containing protons and neutrons, surrounded by electrons in orbit. The properties of atoms are determined by the number of protons in the nucleus, which dictates the element the atom belongs to.
This is the atomic orbitals theory.
