~Ionic bonds- a type of chemical bond that involves the electrostatic attraction between oppositely charged ions
Ex: Sodium and fluorine to form sodium fluoride. Sodium loses its outer electron to give it a stable electron configuration
~ Covalent bonds- a chemical bond that involves the sharing of electron pairs between atoms.
Ex: covalent bond forming H2 (right) where two hydrogen atoms share the two electrons
~ Metallic bonds- the sharing of free electrons with a group of atoms of positively charged ions
