sublevel

“it is impossible to know the exact location of an electron at any given point in time”

heisenberg uncertainty principle

“no 2 electrons are located in the same location spinning the same direction”

Pauli Exclusion Principle

atoms are more stable with a full valence level

octet rule

atoms are more stable if their electrons are close to the nucleus

aufbau principle

“each sublevel of equal energy receives one electron each before pairing begins”
