An atom a fundamental piece of matter. (Matter is anything that can be touched physically.) Everything in the universe (except energy) is made of matter, and, so, everything in the universe is made of atoms.

John Dalton was the first to adapt Democritus' theory into the first modern atomic model. J.J Thomson was a physicist who is credited for discovering the electron. He used his research on cathode ray tube technology in this discovery. 3.

The next major advance in the history of the atom was the discovery of electrons. These were the first subatomic particles to be identified. They were discovered in 1897 by a British physicist named J. J. Thomson

Of course jiggling atoms are also critically important in chemical reactions. The fact that atoms cannot be created or destroyed in chemical reactions allows for all sorts of important predictions. ... Every atom is composed of some number of electrons orbiting a heavy but small nucleus.

The first major discovery that set off modern atomic theory was that atoms aren't in fact the smallest things that exist.

Electrons are found in shells or orbitals that surround the nucleus of an atom.Protons and neutrons are found in the nucleus. They group together in the center of the atom.

The fact that atoms cannot be created or destroyed in chemical reactions allows for all sorts of important predictions. Atoms form the smallest building blocks of chemistry, and they combine to form an infinite variety of more complicated structures, however it turns out atoms are not the smallest pieces of matter.
