FoundationWhich statement best contrasts the Bohr model with the modern quantum-mechanical model?
Need a small nudge?

The models describe electron location differently.

UnderstandingWhich description correctly assigns the four quantum numbers?
Need a small nudge?

Three characterize an orbital; one characterizes an electron’s spin.

ApplicationWhat does the Pauli exclusion principle require for electrons in one atom?
Need a small nudge?

Compare the complete four-number labels of two electrons.

InterpretationHow does Hund’s rule place three electrons into three degenerate p orbitals?
Need a small nudge?

Degenerate orbitals have equal energy.

ConnectionGround-state oxygen has electron configuration 1s² 2s² 2p⁴. How many unpaired electrons does it have?
Need a small nudge?

Apply Hund’s rule to four electrons distributed among three 2p orbitals.
