When the atomic nuclei of a pair of aluminium nuclei are fused the element produced is?
This could only be deduced from theory, there is no way this could be done on earth. Aluminium has 13 protons and 14 neutrons, if you put two of these together you get Iron 54 which does occur in nature as a small percentage of natural iron (mostly Fe56) and has a very long half life. Maybe that has come from such a fusion.
