- - - - Many strong covalent bonds between atoms make up giant covalent structures. The atoms are joined to each other in a regular arrangement.
    - - They have high melting points, and no conductivity. They have no overall charge.
    - - Silicon dioxide
  - - - Ions exert their electrostatic force of attraction in all directions. Therefore, solid ionic substances are made up of giant lattices of ions.
    - - Sodium Chloride
    - - They have very high melting and boiling points. They can conduct electricity when melted or dissolved in water.
  - - - Strong metallic bonds are strong electrostatic attractions between the positive metal ions and the surrounding negative electrons. It consists of ions in a sea of electrons.
    - - They have high melting and boiling points. They're conductive and malleable.
    - - Magnesium
- - - - Water
    - - Covalent bonding occurs when pairs of electrons are shared by atoms. Atoms will covalently bond with other atoms in order to gain more stability, which is gained by forming a full electron shell.
    - - Covalent compounds have bonds where electrons are shared between atoms. Due to the sharing of electrons, they exhibit characteristic physical properties that include lower melting points and electrical conductivity compared to ionic compounds
