- Electron StructureElectrons are arranged within shells around the nucleus.
- Filling of Orbitals and Electron PairingOrbitals fill in order of increasing energy.
- Ionic BondingIonic bonding is the electrostatic attraction between oppositely charged ions.
- Structure and Properties of Ionic CompoundsIons attract oppositely charged ions in all directions resulting in a giant ionic lattice.
- Covalent BondingA covalent bond is a localised bond formed as a strong electrostatic attraction between a shared pair of electrons and the nuclei of the bonded atoms.
- Single, Double and Triple BondsPairs of electrons that are not involved in covalent bonding are called lone pairs.
- Dative Covalent BondsA dative covalent bond or a co-ordinate bond is a covalent bond in which the shared pair of electrons has been supplied by only one of the bonding…
