HEY FRIEND ANSWER IS....

The easiest way to explain it is that AlAl has one unpaired electron in it's highest energy orbital (3p3p), and MgMg's highest energy orbital (3s3s) the electrons are paired. It is energetically favorable for all the electrons in an orbital to be paired, which means that breaking up this pair would require more energy.
