1. Which of the following statements is correct? a. The transition metals have little variability in their ionization energies and electronegativities due to their similar valence electron shells. b. Transition metals are characterized by the formation of many diamagnetic compounds due to the presence of unpaired d electrons. c. One difference between transition metals and main group metals is the latter’s ability to form coordination complexes. d. Transition metals are characterized by many oxidation states due to the high reactivity of the unpaired d electrons.

b. Transition metals are characterized by the formation of many diamagnetic compounds due to the presence of unpaired d electrons.
c. One difference between transition metals and main group metals is the latter’s ability to form coordination complexes.
d. Transition metals are characterized by many oxidation states due to the high reactivity of the unpaired d electrons.
2. Which of the following statements about atomic radii accurately describes the data in the photo attached?
a. The elements right after the d-block experience an expansion due to the repulsion created by the d electrons such that period 4 nonmetals are substantially larger than period 3 nonmetals.
b. The minima of the graph correspond to the halides because they have the greatest effective nuclear charge.
c. The transition metals have relatively the same atomic size moving across the group because their valence shell, which is the s orbital, essentially remains the same.
d. The peaks of the graph correspond to the noble gas configurations because they have fully-filled orbitals.
