  • Covalent bonding is the bonding between non-metal atoms.
  • Covalent bonds form when the atoms share electrons so that both atoms achieve full outer shells
  • Substances formed with covalent bonding have simple molecular structures.
  • The atoms are held together by very strong covalent bonds.
  • The forces of attraction between these molecules are very weak. So melting and boiling points are very low.
  • Most simple molecular substances are gases or liquids at room temperature.
  • Simple molecular substances don't conduct electricity, because they have no free electrons or ions.
  • Simple molecular substances are usually quite insoluble in water.
