Subatomic Particles Quiz

According to the Pauli Exclusion Principle, how many electrons can occupy a single orbital?

• 1

• 2

• 3

• 4

According to Hund's Rule, if three electrons are to be placed in the 2p subshell, how will they be distributed?

• All three in one orbital with opposite spins.

• Two in one orbital and one in another.

• One in each of the three orbitals with parallel spins.

• All three in one orbital with parallel spins.

Hund's Rule of Maximum Multiplicity states that:

• Electrons will fill the lowest energy orbitals first.

• Electrons will pair up in an orbital only when all orbitals in the same subshell have one electron.

• No two electrons in an atom can have the same set of four quantum numbers.

• Electrons will fill orbitals starting with the highest energy level.

Which element is likely to have the largest atomic radius?

• Fluorine (F)

• Lithium (Li)

• Carbon (C)

• Neon (Ne)

Hund's Rule of Maximum Multiplicity is important for determining:
