The atomic radius of F, Br, and I are 64, 114, and 138 pm respectively. From this information (and not your
book) estimate a reasonable atomic radius of Cl.
Use the periodic table (not any tables in your book) to predict which element has the largest ionization energy.
Use the periodic table (not any tables or charts in your book) to predict which element has the largest atomic

Which of the following is a transition element?
The element germanium is used in the manufacture of some transistors. What other element might be used for
such a purpose?
For which of the properties does Li have a larger value than potassium? Use the periodic table (not the tables
or charts in your text.)
first ionization energy
number of protons
The energy needed to remove the first electron from an atom is the first ionization energy. The energy needed
to remove the second electron from an atom is the second ionization energy. The definition of third and fourth
ionization energies is similar. Which of the atoms below would you expect to have the largest 3rd ionization
