IB Chemistry SL 1.3.2 Hydrogen emission spectrum
Practise the hydrogen spectrum as exam evidence for quantized energy levels, electron transitions and the convergence of lines at higher energy.
How this is tested
- identify hydrogen line spectra as evidence for discrete energy levels
- explain emission lines as electrons falling to lower levels and releasing photons
- use converging spectral lines to show that higher energy levels become closer together
