Ionization Energy & Electron Affinity

Ionization Energy & Electron Affinity on Periodic Table

Sort of like what happened with electronegativity, the periodic table won't give you a number for ionization energy of each element. But almost all chemistry teachers require you to know the general trends of ionization energy, and you'll need to be able to compare two atoms and say which one has a higher first and second ionization energy.

Ionization Energy Calculations Using Rydberg Equation

One of the many uses of the Rydberg equation (oh what a wonderful equation!) is calculating the ionization energy of a hydrogen atom. What fun! What splendor! Quick man, to the calculators!
