Solids are made up of densely packed atoms and gases have atoms that are more spread out. There are three basic parts of an atom: electrons, protons and neutrons.
Electrons are the smallest of the three particles that make up atoms. Electrons are found in the 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. Each unique element has an atomic number equal to the number of protons it contains.
Atoms can join together to form molecules which in turn form most of the objects around you. Different elements like oxygen and carbon contain different kinds of atoms.
