Since, the metallic character decreases along a period from left to right, therefore, metallic character increases in the order: Ge < Ga < Ca < K (as all these belong to same period). Now we compare the metallic character of Ca and Mg. Since, metallic character increases down the group form the top to bottom; therefore, Ca is more metallic than Mg.
