What you practice

These are the CBSE Class 11 Structure of Atom skills this quiz is built around.

Compare Thomson, Rutherford and Bohr models by evidence and limits.
Assign four quantum numbers and electronic configurations correctly.
Relate hydrogen spectra, de Broglie and Heisenberg ideas to orbitals.

A useful tip

Hund rule fills degenerate orbitals singly before pairing. That single-first filling explains why nitrogen carries three unpaired electrons while oxygen carries only two.
