Both calcium and magnesium are alkaline earth metals which belong to 2nd group of the long form periodic table. Their atomic numbers are Mg = 12 and Ca = 20. So, obviously, it is Ca that follows Mg in that group.
Now, as we know very well, metallic nature increases from top to bottom in a group of the periodic table. Hence calcium is more metallic than magnesium.
Again, oxides and hydroxides of metals are basic and those of nonmetals are acidic. Moreover, more is the metallic nature of the element, higher will be the basic nature of its oxide and hydroxide. Thus, CaO is more basic than MgO.
