Can someone please explain to me ionization energy?

Ionization energy is the energy needed to remove an electron from an atom in the gas phase. So it's looking at how strongly a nucleus is holding on to its electrons. The easier it is to remove an electron the lower the ionization energy will be. For example elements in the first column want an octet so their ionization energy is low and it is easier to take an electron from one of those atoms compared to an atom in the 17 column. So by this we can see that ionization energy decreases down the rows and increases across. Hope this helped!

ionization energy is the energy required to remove an electron from its orbital.
so it would take a lot of energy to remove an electron from a full orbital (an octet) and it would take little energy to remove an orbital that only has 1 electron.
