Choose one of the transition or inner transition metals from the periodic table. Discuss why your transition metal and their compounds display a variety of color. Be sure to include in your discussion, important oxidation states, the electron configuration and how the d-electrons are involved. How can you include the electromagnetic spectrum and the nature of light into your discussion? How is energy and wavelength related? Use your knowledge of the emission and absorption of light. HELP!!!!!!

Select all the true statements. None of the period 4 transition metals, except Cu, are active enough to reduce H+ from aqueous acid to form hydrogen gas. Lanthanide contraction is responsible for the shrinkage in atomic size between a group in period 5 to period 6. Period 6 contains some of the densest elements known. Many transition metal compounds are colorless and diamagnetic.
