Ionization Energy
Define Ionization Energy: It is the energy required to remove an electron from an atom.
Explanation:
The more energy levels an atom has, the easier it is to take electrons from their
outermost energy levels. They are able to "protect" the energy levels very
close to them, so it takes more ionization energy to take electrons from an
atom with less energy levels (like Hydrogen) and easier to take electrons from
an element like Francium.
