Electrons occupy orbitals of lowest energy first is part of what electron configuration rule?
Hund’s Rule
Aufbau Principle
Pauli Exclusion Principle
Mr Serena's 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 only if the electrons 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
States that a maximum of one electron can occupy a single atomic orbital
What does Hund's rule state?
States that single electrons must fill only one orbital at a time before moving on
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 electrons have opposite spins
States that single electrons with the same spin must occupy each energy orbital before additional electrons with opposite spins can occupy the same orbitals
