Electronic configurations of multielectron atoms Having established the modern/quantum mechanical picture of the atom, let’s now turn our attention to how this principle relates to the groups and period of the periodic table. 18 group periodic table.

Electronic configurations of multielectron atoms Aufbau principle: o Lower energy orbitals fill before higher energy orbitals. o An orbital can only hold 2 electrons which must have opposite spins. o If two or more degenerate orbitals are available, one electron goes into each orbital, until all are ½ fill (Hund’s rule). Only then does a 2 nd electron fill one of the orbitals. Each of the singly occupied orbitals must have the same spin quantum number.
