According to Fajan's Rule, with increase in positive charge on the cation the covalent character increases. Since, Al3+Â has high positive charge than Mg2+Â which in turn has high positive charge than Na+, the trend in polarising power is:Â Al3+Â > Mg2+Â >Â Na+

Just remember 3 imp points from fajan rule
- Anionic part should be greater than the cationic part
- Cationic part should be small 3.-ve charge on the anion
This all favours increase in covalent character
