As the energy of 3d orbital is higher than 4s, the last two electrons in calcium get accomadated in 4s energy level instead of 3d . It is because of this order in which the atomic orbitals are filled as stated in Afbau's principle that the electronic configuration of calcium is 2, 8, 8, 2 and not 2, 8, 9, 1 or 2, 8, 10.
