Why does group 1 have the lowest ionization energy? As a result, li has a significantly smaller first ionization energy than helium. Which element has the highest first ionization energy? The ionization energy decreases from top to bottom in groups, and increases from left to right across a period. Cesium has atomic number 55 and is in the fifth row of the periodic table. Group 1 of the periodic table features metals whose valence electron singly occupies the outermost shell, the valence shell of the given atoms.
