I've answered another one of your questions with the content of how to work these out
Answer:
Because as we move down the group size/ radius of atom increases due to increase in shells and screening effect. The hold of nucleus on valence electrons decreases and effective nuclear charge decreases so it is easy to remove electron from greater sized atoms as compared to smaller sized aroms.
Energy required to remove electron is ionization energy so greater sized atoms have low ionization energy.
