it is bigger..so it has more electron in orbit than smaller atom...so it keep simple
Potassium has a low ionization energy.
The fewer numbers of valence electrons, and the farther away those valence electrons are from the nucleus, the lower the ionization energy will be. So your group 1 and 2 metals toward the bottom of those groups will have low ionization energies, and therefore be very reactive.
The ionization energy of aluminium is 5,985 77 eV. It is a medium energy.
It is " bigger " because it has more electrons in orbit around it. So, to keep things simple and away from such concepts as shielding, we know that the farther electrons are from the nucleus the looser they are held and to ionize this element is easier, thus lower ionization energy needed.
The first ionization energy is the energy that is required in order to remove the first electron from an atom in the GAS phase, the second ionization energy is the energy required to remove the second electron from an atom in the GAS phase. Ionization energy will generally increase for every electron that is removed and increases from left to right in the periodic table and moving up the periods.

Low

The ionization energy tells us about the energy required (and thus the ease) with which an atom/ion can give away an electron (in the outermost shell). So, atoms with low ionization energies ( lowest for Caesium) give away the electron with ease
high
It would not take a great deal of electronegativity to pull at least the first electron off this atom.

No. Nonmetals have a high first ionization energy.

low
a process where in positive ions are formed. Here, the electrons orbiting the outer-most shell of an atom are knocked out, resulting in the atom having more protons than electrons. This creates a positive ion.
