Out of sodium potassium rubidium and cesium Which element has the greatest ionization energy?

∙ 11y ago
Sodium has the greatest ionization energy of the four elements listed from column 1 of a wide form Periodic Table. Among this group of metals that readily form cations, the largest always has the lowest ionization energy and the smallest has the most. This is generally ascribed to the fact that the valence shell electron is further from the nucleus in the largest element and nearest in the smallest element.

What element has the larger first ionization energy cesium or potassium?
Potassium has a higher ionization energy than cesium.
The atomic radius of potassium is smaller than the atomic radius of?
Rubidium; the next higher atomic numbered element in the same column of the periodic table always has a higher atomic radius, with some exceptions among transition elements due to the "lanthanide contraction". However, potassium and rubidium are not transition elements.
