(c) Electronic configuration of Mg (atomic number = 12) 2, 8, 2 Electronic configuration of Na (atomic number = 11)2, 8, 1 Electronic configuration of K (atomic number=19) 2, 8, 8, 1 Electronic configuration of Ca (atomic number =20) 2, 8, 8, 2 From the above electronic configurations, it is clear that K and Na will lose electron easily to achieve stable configuration. But out of K and Na, K will lose electron more easily because the force of, attraction on valence electron of K is least among the given elements.
