- 1Atomthe fundamental building block of all material, it consists of a cluster of protons and neutrons surrounded by a cloud of electrons
- 2atomic modelscientists' representation of an atom determined by experiment and indirect observation
- 3atomic numberthe number of protons in a nucleus, the atomic number determines what type of atom it is
- 4compounda pure substance that is made up of two or more different types of atoms which are chemically joined
- 5crystal latticea grid-like structure of atoms or ions where each particle is bonded to all of its neighbouring atoms
- 6electrona small negatively charged particle, clouds of electrons surround the nucleus of the atom
