|---|---|
| Define Aufbau's principle | An electron enters the orbital with lowest energy first and subsequent electrons are fed in the order of increasing energies. |
| Define Hund's rule | Every orbital is singly occupied with one electron before any one orbital is doubly occupied, and all electrons in singly occupied orbitals have the same spin. |
| Define Pauli's exclusion principle | No more than two electrons can occupy the same orbital and two electrons in the same orbital must have opposite spins |
| Define electrostatic forces | The attractive or repulsive force between two electrically charged objects. |
