Electrons occupy orbitals of lowest energy first is part of what electron configuration rule?
Hund's Rule
Aufbau Principle
Pauli Exclusion Principle
Hund’s rule states…
Atomic orbitals have opposite spins and 2 electrons each
Electrons occupy orbitals of highest energy first and energy level changes as you go up
Electrons occupy orbitals of lowest energy first, starting with 1s
Electrons occupy orbitals of equal energy, one electron enters EACH orbital ONE AT A TIME until orbitals of the entire energy level have one electron with the SAME SPIN.
What is the Pauli Exclusion Principle?
An atomic orbital can only hold a maximum of 2 electrons, each with opposite spins
An atomic orbital can hold a minimum of 6 electrons, each with opposite spins
An atomic orbital can hold a maximum of 6 electrons, each with the same spin
An atomic orbital can hold a minimum of 2 electrons, each with opposite spins
