energy levels,sub levels, and orbitals
Define orbital.
A region in an where there is a high probability of finding electrons
How many electrons are in the s orbital?
2 electrons
What is the noble gas notation for nitrogen?

What is the hunds rule?
Electrons in the same sublevel occupy empty orbitals first before pairing up. Unpaired electrons must have the same spin.
Define sublevel.
S,p,d, and f- each energy level has a certain number of these, and each has a different shape and number of orbitals

What causes Pauli exclusion principle?
two electrons in the 1s orbital are each unique and distinct from one another because their spins are different
