QuestionAnswer
the ways in which electrons are arranged into various orbitals around the nucleus electron configurations
aufbau principle electrons occupy the orbitals of lowest energy first
Pauli exclusion principle an atomic orbital can describe at most two electrons
Hund's rule one electron enters each orbital of a sublevel until all orbitals contain an electron with the same spin direction
Sublevels of a lower principal energy level may _____ the sublevels of a higher principal energy level overlap
Some actual electron configurations differ from the aufbau principal because half-filled and filled sublevels are more _____ than other configurations stable
Exceptions to the aufbau principle are due to subtle _________ interactions in orbitals with very similar energy levels. electron-electron
Two elements whose electron configurations do NOT follow the aufbau principle are ___ and ___. Copper and chromium
