From Se 2- ion, ground-state electron configurationhas to be given. Concept introduction: By using aufbau principle, electrons starts to occupy from orbitals oflower energy level. Thus, the obtained lower energy configuration is known as ground-state electron configuration. Aufbau principle: Electrons first occupy orbitals with lower energy than higher energy. An orbital can be occupied only by two electrons having opposite spins. Each electron fills each orbital till it is half filled, when they are degenerate orbital. This is called as Hund’s rule. The order of electrons filling in an atom is given as Figure 1
