WebThe Fermi level is the highest occupied energy level at absolute zero, that is, all energy levels up to the Fermi level are occupied by electrons. Since fermions cannot exist in identical energy states ( see the exclusion principle ), at absolute zero, electrons pack into the lowest available energy states and build up a " Fermi sea " of electron energy … WebThe ground state electronic configuration of Neutral Vanadium atom is [Ar] 3d3 4s2. The portion of Vanadium configuration that is equivalent to the noble gas of the preceding period, is abbreviated as [Ar]. For atoms with many electrons, this notation can become lengthy and so an abbreviated notation is used. 5.
