Pauli's principle says no two electrons in an atom can share the same set of:
ASix quantum numbers
BFour quantum numbers
CFive quantum numbers
DThree quantum numbers
Answer & Solution
Correct answer: B. Four quantum numbers
1. Each electron must differ from every other in at least one respect.
2. No two electrons in an atom can have the same set of four quantum numbers.
3. So the correct answer is four quantum numbers.
