Helium

Explanation:

Ionization potential is the energy needed to remove and electron

The elements with highest value of first ionization potential are the noble gases because they want to stick to their electrons as much as possible and retain their stability

Now, in the noble gases Helium has the highest IP (Ionization Potential) because its very small and the nucleus which is positive can attract its electrons a lot easier and retain them. Obviously it would be hard for the nucleus to retain an electron which is far away because the attractive forces would be less.
