Ionization energies
- Energy required to remove the most loosely held electron from one mole of
gaseous atoms to produce 1 mole of gaseous ions, each with a charge of 1+
- The opposite are electron affinities
- Affected by three things
- Effective nuclear charge
- Effect of sheilding from the other shells
- Distance from the nucleus
- All are endothermic
- Positive enthalpy change
