Answer 1

Magnesium is the compound. It belongs to the 2nd group of the periodic table. The compond it forms with the radicals are - MgSO4 and Mg3(PO4)2.With NO3 , it shall form Mg(NO3)2.All the bonds formed are ionic bonds because MgSO4,Mg3(PO4 ) and Mg(NO3)2 is an ionic compound since magnesium is a metal, and SO4 is considered a non-metal. Covalent compounds occur between two non-metals.
