The Quantum Atom

These questions cover the quantum atom skills that school trial papers test again and again: Bohr's postulates, energy level diagrams, the Rydberg equation, emission and absorption, series limits, de Broglie wavelengths, electron diffraction and the limits of each model. Use $R=1.097\times 10^7$ m⁻¹, $h=6.626\times 10^{-34}$ J s, $c=3.00\times 10^8$ m/s, $q_e=1.602\times 10^{-19}$ C, $m_e=9.109\times 10^{-31}$ kg and $E_n=-\frac{13.6}{n^2}$ eV for hydrogen. They start easy and get harder. Stuck? Tap Show a hint for one step at a time.
