- Ionic
- Electrons are donated to another atom, they are not shared.
- Properties: Brittle, high melting and boiling points, conduct electricity only when dissolved or molten, good thermal insulators, forms crystals.
- forms ionic lattices.
- Examples: NaCl, KI, KBr, KF
- Covalent
- Properties: Low melting and boiling points, Insoluble in nonpolar solvents except water, poor electrical conductors.
- Electrons are shared between atoms.
- Example: H2O, C2H6, CO2, I2, H2
- Dative covatent: Both electrons shared in the bond are from the same atom.
- Polar covalent
- Difference in electronegativity causes electrons to be pulled towards one atom. this creates a polar bond. these polar bonds form polar molecules only when the molecule is asymetric.
- Examples: H-Cl, O-H, C-Cl
- Ionic
