85. For C (Z = 6) write down the appropriate electron configuration. Using the Pauli principle derive the allowed electronic states for the 4 outermost electrons. Express these states in conventional atomic notation and order in energy according to Hund’s rules. Compare this with a (2p)⁴
configuration.
