1. Aufbau's rule states that electrons fill orbitals with lower energy levels first before filling higher energy levels.
2. The s subshell is filled first.
3. In an s orbital, a maximum of 2 electrons can fit.
4. In a p orbital, a maximum of 6 electrons can fit.
5. In a d orbital, a maximum of 10 electrons can fit.
6. In an f orbital, a maximum of 14 electrons can fit.
7. Hund's rule states that when filling orbitals of the same energy level, electrons will occupy separate orbitals of the same energy before pairing up in the same orbital.
8. Electrons maximize the number of unpaired electrons because it is energetically favorable. Having unpaired electrons means that they have the same spin, and this increases the stability of the electron configuration.
