Solution: Of those shown, Helium has the largest ionization energy and Cesium has the lowest. Hydrogen is much higher than other group 1 elements. The ionization energy of polonium is 812, Iodine is 1008, and Radon is 1037. An accessible periodic table can be found here: https://media.pearsoncmg.com/bc/bc_0media_chem/periodictable/table.html
Figure Trends in first ionization energies of the elements.
The value for astatine, At, is missing in this figure. To the nearest 100 kJ/mol,what estimate would you make for the first ionization energy of At?
