Bonding
- Ionic
- definition: bond between a metal and a non metal
- electrostatic attraction between opposite charges (+/-) formed as a result of electron transfer
- positive ions (cations) and negative ions (anions)
- giant lattice structure formed. For example, Sodium Chloride (NaCl)
- Covalent
- definition: electrostatic attraction of two nuclei with a shared pair of electrons
- Macromolecular structures
- many atoms joined together by very strong covalent bonds- e.g. diamond and graphite
- Simple Molecules
- weak intermolecular forces, however strong covalent bonds
- determine melting and boiling point
- Dative Covalent/ Co-ordinate Bond
- definition: both of the shared electrons are from the same atom in a covalent bond
- Metallic
- definition: electrostatic attraction between positively charged metallic cations and delocalised electrons
