Ionic bonding

  • It has a high boiling and melting point.
  • Strong electrostatic forces.
  • It's really hard.
  • Giant lattice structure.
  • It conducts electricity.
  • Eg: NaCl (Group 1 and 7 put together)

Covalent Simple Molecules Bonding

  • Weak intermolecular forces.
  • Low melting and boiling points.
  • Doesn't conduct electricity. (No overall charge.)
  • In form of liquid or gas.
  • Made of molecules.
  • Eg: H2O

Covalent Macromolecules Bonding : Diamond

  • Doesn't conduct electricity.
  • Very hard.
  • Has a high boiling and melting point.
  • C-C bonds
  • Has a giant lattice structure.
  • Every C got four bonds.

Covalent Macromolecule Bonding : Graphite

  • Weak between the layers.
  • Has a high melting and boiling point.
  • Conducts electricity.
  • Eg: Silica
  • Layers that slide.
  • Free electrons.

Metallic Bonding

  • Strong electrostatic forces.
  • De-localised electrons/free electrons; giant structure of atoms, layers that slide.
  • High melting and boiling point.
  • Conducts electricity.
  • Eg: Fe
  • Hard and malleable
