Thallium, a neurotoxin, is the heaviest member of Group 13 of the periodic table and is found most usually in the +1 oxidation state. Aluminium, which causes anaemia and dementia, is also a member of the group but its chemical properties are dominated by the +3 oxidation state. Examine this issue by plotting the first, second, and third ionization energies for the Group 13 elements against atomic number. Explain the trends you observe. Hints: The third ionization energy, I3, is the minimum energy needed to remove an electron from the doubly charged cation: E2+(g) → E3+(g) + e−(g), I3 = E(E3+) − E(E2+). For data, see the links to databases of atomic properties provided in the text’s website.
