5.2

When electrons occupy orbitals of equal energy, one electron enter each orbital until all the orbitals contain one electron with parallel spins.

Hund's rule

The various orbitals within a sublevel of a principle energy level are always of... energy.

consistent

the most stable arrangement of electrons around the nuceus of an atom.

electron configuration

The ways in which the electrons are arranged around the nuclei of the atoms are called..

electron configurations

To occupy the same orbital two electrons must have...spins

opposite

When using the shorthand method for showing the electron configuration of an atom,...are used to indicate the number of...occupying each sub level.

superscripts/e-s

Electrons enter orbitals of lowest energy first.

Aufbau principle

The...describes the sequence in which orbitals are filled.

Aufbau principle

An atomic orbital may describe at most two electrons.

Pauli exclusion principle

The...principle states that a maximum of only...electrons can occupy each orbital

Pauli exclusion/2

Hund's rule states that the electron pair up only after each orbital in a sub level is occupied by...

an electron
