Question The transition metals are found in the d-block of the periodic table. Based on trends in reactivity observed in the periodic table, as we move from the left hand side of the first row of the d-block (Element = Sc, Group 3) to the far right hand side of the same row (Element = Zn, Group 12), what happens to the ionic radii for the elements in the 2+ oxidation state? A. There is no real trend in ionic radii for this series of M2+ ions. B. The ionic radii of the M2+ ions gradually decrease from Sc to Zn. C. The ionic radii of the M2+ ions gradually increase from Sc to Zn.

Question

The transition metals are found in the d-block of the periodic table. Based on trends in reactivity observed in

the periodic table, as we move from the left hand side of the first row of the d-block (Element = Sc, Group 3) to the far right hand side of the same row (Element = Zn, Group 12), what happens to the ionic radii for the elements in the 2+ oxidation state?

A. There is no real trend in ionic radii for this series of M2+ ions.

B. The ionic radii of the M2+ ions gradually decrease from Sc to Zn.

C. The ionic radii of the M2+ ions gradually increase from Sc to Zn.
