• 1 electron

• 2 electrons

• 3 electrons

• 4 electrons

What must be true about the spins of the two electrons in an orbital according to the Pauli Exclusion Principle?

• They must be the same

• They must be opposite

• They can be either same or opposite

• Spin is not considered

What does Hund's Rule suggest about filling orbitals within a sublevel?

• Fill all orbitals with two electrons before adding any single electrons

• Fill each orbital with one electron before pairing them

• Electrons prefer to fill higher energy orbitals first

• Electrons can fill any orbital in any order

What analogy is used to describe Hund's Rule?

• Filling a water bottle

• Empty Bus Seat Rule

• Filling a swimming pool

• Stacking books

How many electrons can occupy a single orbital according to the rules discussed?

• 3 electrons

• 1 electron

• Unlimited as long as they have opposite spins
