We’re asked to make an estimate for the first ionization energy of astatine, At to the nearest 100 kJ/mol, based on the given figure.
Recall that Ionization energy is the energy required to remove an electron from a gaseous atom or ion.
The trend of the ionization energies of the elements can be observed in the periodic table:
• increases going from left to right of a period
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?
