| Force | Model | Basis of Attraction | Energy (kJ/mol) | Example |
| Intramolecular | ||||
| Ionic |  | Opposite charges | 4000 – 400 | NaCl |
| Covalent |  | Nuclei – shared e- pair | 1100 – 150 | H - H |
| Metallic |  | Metal cations and delocalized electrons | 1000 – 75 | Au |
Electromagnet force causes the intramolecular reactions to occur. Opposites charges attract and similar charges repel. The intramolecular reactions are ionic covalent and metallic. These each occur with different types of atoms. Ionic boding occurs between a metal and a nonmetal and Metallic bonding occurs between two metals. Covalent bonding allows atoms to share their electrons.
Weak force causes radiation and decay within the atom which causes the matter to change.
Strong force gives an atom shape by helping the atom stay together.
