Francium has the lowest 1st ionization energy. It badly wants to lose that electron. It is extremely energetically favorable. Basically the elements that are in group 1 and are in the lowest periods.

Cesium = 375.7 kJ·mol−1
Cesium wins by a small margin.

What elements have the highest and lowest ionization energy?
Helium has the highest first ionization energy and francium has the lowest first ionization energy.
Which element has the smallest first ionization energy Na K Rb Li?
Lithium has the least number of protons, rubidium has the most number of protons.
Elements that have the highest first ionization energy?
Helium (He) has the highest first ionization energy. Ionization energy increase as you go across the periodic table from left to right
Which of these elements has the highest first ionization energy Si or C?
The ionization energy is the energy needed to extract an electron from an atom; first ionization energy, second, third etc. can be measured. Reactive chemical elements have lower ionization energy.The first ionization energy for silicon is 786,5 kJ/mol.The first ionization energy for carbon is 1 086,5 kJ/mol.
