I am giving you the simplest form of explanation I know.
When the atom is larger the electrons in the outermost orbit are further away from the nucleus and the so the electrons are more loosely held by the nucleus and so it is much easier to remove such electrons rather than the electrons held more tightly by the nucleus.
So, the ionization energy will be lesser if the atom gets larger.
Just in case.... nucleus is positively charged because of the presence of protons in them and the electrons are negatively charged. Opposite charges attract.

if atoms are large then valence electrons are loosely held around it. so less energy is required to release the electrons. obviosly ionization energy is less

Take a look at a periodic table.
Ionization energy values follow trends throughout the periodic table, increasing from bottom to top and left to right in the periodic table.

lower because it takes less energy to lose its valence electron.
