Electrons occupy orbitals of lowest energy first is part of what electron configuration rule?
Hund’s Rule
Aufbau Principle
Pauli Exclusion Principle
What does Pauli exclusion principle state ?
states that each electron occupies the lowest energy orbital available
states that a maximum of two electrons can occupy a single atomic orbital, but if only if the electros have opposite spins
states that single electrons electrons with the same spin must occupy each-energy orbital before additional electrons with opposite spins can occupy the same orbitals
What does Hund's rule states ?
states that single electrons electrons with the same spin must occupy each-energy orbital before additional electrons with opposite spins can occupy the same orbitals
states that each electron occupies the lowest energy orbital available
states that a maximum of two electrons can occupy a single atomic orbital, but if only if the electros have opposite spins
Energy levels are denoted by:
letters
numbers
a combination of letters and numbers
subscripts
