The smallest particle of matter that retains its properties is called the atom.

The atom is composed of a nucleus, surrounded by an electron cloud. Many models explain the structure of the atom and the particles that make it up, including  the familiar model which is widely accepted today.

This video demonstrates the basic model, which was first introduced by Niels Bohr (who won a Nobel Prize for it) and describes atomic composition and its properties.
