It is probably good just to get a complete explanation of it from just Wilipedia or an encyclopedia. It might sink in more if you read a little detail from one of these sources. Good luck...believe it or not chemistry is rather fun
http://en.wikipedia.org/wiki/Ionization_鈥?/a>Also can someone please explain how to figure ionization energies of atoms? What is ionization?
Ionization is the addition or removal of an electron from a element. For example potassium K, can ionize to K+ after losing an electron.
Ionization energy is the energy required to remove one electron from an element. There are also second, third, etc ionization energies for removal of more electrons. In general, elements on the bottom left have the lowest ionization energies. Thus ionization energies increase across a row as more protons are added (outweighs the effect of the addition of another electron due to shielding) and up a group as there is much less e- shielding with less electrons.
Ionization energy is the energy required to remove the outermost electron of an atom. 2nd ionization energy would be energy required to remove the 2nd outermost electron and so on.
And there are charts for ionation energies of certain atoms, so there's no need to calculate
