BONDING
- METALLIC
IONIC
- BONDING
  - METALLIC
- Positively and negatively charged ions bond together to cancel out charges.
COVALENT
INTERMOLECULAR
Shared pair of electrons between two atoms
- COVALENT
Bond is between two non metals such as H20
Sometimes dative covalent bonds form
- Dative Covalent is where both electrons donated come from one atom such as NH4+
Electrostatic force of attraction between positive metal ions and delocalised electrons
The positive metal ions are attracted to the electrons to form a lattice and metallic bonding
Formed between metal and non metal ions.
- IONIC
  - Positively and negatively charged ions bond together to cancel out charges.
Strong electrostatic force between oppositely charged ions.
Three different types- Van Der Waals,Hydrogen and dipole-dipole.
- INTERMOLECULAR
- Dipole Forces are forces between the positive end of one polar molecule, and the negative end of another polar molecule.
Van der Waals' forces are forces of attraction that exists between all atoms and molecules. It is the weakest of the forces.
- Three different types- Van Der Waals,Hydrogen and dipole-dipole.
  - Dipole Forces are forces between the positive end of one polar molecule, and the negative end of another polar molecule.
Sometimes covalent bonds are polar, and so the shared pair of electrons are not equally shared
- One atom will attract the pair of electrons more than the other, depending on its electronegativity
