-insoluble in water
-most dont conduct electricity
what is metallic bonding?
the electrostatic attraction between positive metal ions and negative delocalised electrons
what are allotropes?

what are electrostatic forces? 
forces that hold the atoms in molecules together
what are used to show how covalent bonds are formed? 
dot cross diagrams
what are covalent bonds?
