why does inoinzation energy tend to decrease from top to bottom within a group?

i'm not sure, but i think it has something to do with the size of the element

The electrons involved in ionization, that is, the outermost electrons, are farther away from the nucleus, and are held less strongly. The energy to remove them (ionization energy) is less.
