What does Pauli exclusion principle state ?

states that a maximum of two electrons can occupy a single atomic orbital, but if only if the electros have opposite spins

states that each electron occupies the lowest energy orbital available

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

What is incorrect about this orbital diagram?

There should only be 1 electron in the first 2p box and one in the 2nd 2p box

Both arrows in the 2p box should be pointing up

There is nothing incorrect with this diagram

All the arrows should be pointing up.

What is the shape of a p orbital?

it's just too complex to thing about it

Splitting an atom's nucleus apart

Separating an atom's electrons from its nucleus

Fusing two atomic nuclei together

Splitting an atom's electrons in half

What quantities vary between isotopes of an element?

protons, electrons, and atomic mass

protons, electrons, and atomic number

An atom is electrically neutral when

protons and electrons are the same

protons and neutrons are the same

neutrons and electrons are the same

neutrons balance the protons and electrons
