The first symbol represnts the compound magnesium iodide (MgI2) and the second symbol represents aluminum fluoride (AlF3)
Aluminium iodide is covalent because the electron pair is easily dragged away from the iodide ion. On the other hand, aluminium fluoride is ionic because the aluminium ion can't polarise the small fluoride ion sufficiently to form a covalent bond.
Cl has large anion size its polarizibility is higher than fsa it forms covalent compds
It would be, if it were covalent. However, due to the large difference in electronegativity, any compound of aluminum and fluorine would be ionic. This compound would then be called aluminum IV fluoride. Aluminum does not readily form a 4+ ion, but rather forms a 3+ ion, so the correct formula for aluminum fluoride is AlF3.
