(12) Show the formation of the ionic compound Aluminum Oxide: i)use either
the LCM or Criss-Cross Method to establish the formula. ii)Show the transfer of
electrons and the formation of the cation(s)/Anion(s) in ionic bond formation.

Aluminium belongs to the group 3 and has the atomic number of 13. So it has an electronic configuration of [Ne] 3s2 3p1. So its valence shell has 3 electrons which can be donated to form the Al3+ cation.

On the other side, oxygen belongs to the group 16 with atomic number of 8. It has the electronic configuration of [He] 2s2 2p4. So it has 6 electrons in its outermost shell which can receive another 2 to form the stable octet.

So both aluminium and oxygen reacts to form the aluminium oxide whose formation is shown in the diagram. Both the images are taken from Google.
