Intramolecular forces are the forces that hold atoms together within a molecule. They include covalent, ionic, and metallic bonds.
Covalent Bond: A type of chemical bond where two atoms share one or more pairs of electrons.
A type of chemical bond formed through an electrostatic attraction between two oppositely charged ions.
Metallic Bond: A type of chemical bond formed between positively charged metal ions and delocalized, 'free' electrons in the metal.
