- Atoms
- Atoms have a very small radius
- They contain a positively charged nucleus made up of protons and neutrons
- The protons and neutrons are surrounded by negatively charged electrons
- Protons have an electrical charge of +1
- Electrons have an electrical charge of -1
- Atoms are made of equal numbers of protons and electrons, so they have no electrical charge
- The nucleus of an atom contains most of the mass, but its radius is less than 1/10,000 of the radius of the atom
- The atoms are arranged at different distances from the nucleus (in different energy levels)
