Exam points

  • Interpret ionization-energy data and a spectral convergence limit to identify the ionization threshold and estimate first ionization energy.
  • Explain first-ionization-energy periodic and group trends using nuclear charge, electron shielding, subshell occupancy and distance from the nucleus.
  • Calculate first ionization energy or the corresponding wavelength/frequency from spectral data using E=hf and c=fλ with consistent units.
