Electron Configuration Principles and Rules

To list the chemical properties of elements

To display the order of orbitals based on energy levels

To show the atomic mass of elements

To provide the atomic number of elements

The orbital with the most electrons

The orbital closest to the nucleus

The lowest energy orbital

The highest energy orbital

Only one electron can occupy an orbital

Electrons must have opposite spins in the same orbital

Electrons must have the same spin in an orbital

Electrons can occupy any orbital regardless of energy

Electrons pair up immediately

Electrons fill the lowest energy orbital first

Electrons spread out before pairing

Electrons fill the highest energy orbital first
