Mg is 3 and they are two electrons in its outermost energy level. On the other hand, energy level of Ca is 4 and there are two electrons in its outermost level. In spite same number of electrons in their outermost levels, attraction between the nucleus and valence electrons of Mg is higher than that of Ca.
