Atoms/Molecules

Protons have a positive charge, Neutrons have no charge, and Electrons have a negative charge. Atoms are made of Protons, Neutrons, and Electrons. An atom has a nucleus at its center, which is made of protons and neutrons. Electrons surround the nucleus, going in an orbital, which is like an orbit, but random and 3D.
