When writing the ground-state electron configuration of a many-electron atom, three main rules must be followed: . The aufbau principle: Electrons are added to the lowest energy orbitals available. . The Pauli exclusion principle: No two electrons in an atom can have the same set of four quantum numbers (n. l. me, and m₂). • Hund's rule: For degenerate orbitals, the lowest energy state is attained when the number of electrons with the same spin is maximized. So for a degenerate set of orbitals, one electron goes into each orbital until all the orbitals of the subshell are half-filled. Once all the orbitals of the subshell are half-filled the pairing of electrons can take place. Note that aufbau is the German word for "building up." ▾ Part A Classify each orbital diagram for ground-state electron configurations by the rule or principle it violates. Drag the appropriate items to their respective bins. View Available Hint(s) Aufbau violation 3p 111 3p 111 3p 11 3s 11 45 1 Hund violation…
