Topic 12 Atomic structure HL

12.1 Successive ionisation energies 
Picture
Understandings:
Trends in first ionization energy across periods account for the existence of main energy levels and sub-levels in atoms.
Successive ionization energy data for an element give information that shows relations to electron configurations.
Applications and skills:
Deduction of the group of an element from its successive ionization energy data.
Explanation of the trends and discontinuities in first ionization energy across a period.
Evidence from ionisation energies worksheet

12.1 Calculating ionisation energy
Picture
Understandings:
In an emission spectrum, the limit of convergence at higher frequency corresponds to the first ionization energy.

Applications and skills:
Solving problems using E=hv.
Calculation of the value of the first ionization energy from spectral data which gives the wavelength or frequency of the convergence limit.
Calculating ionisation energy worksheet
