Both occur from Cr 3+ Acidic Basic on: MnO 4 - will oxidize Cr 3+ in acidic solution. The products are Mn 2+ and ______? Answer: A, because it is in acidic solution, see above Both are basic oxides Chem 6C: Lecture Notes May 6, 2009 Chapter 16: The “d” block elements Work Horse Elements: Fe, Cu: industrial metals Ag, Pt, Au: Precious metals Co, Mo, Zn: Vitamins and cofactors for different enzymes Transition metals are the transition between the reactive S block and the less reactive P block, so their reactivity lies in between. The reactivity of a transition metal depends on how the d orbitals are filled. Group 12 has filled d orbitals Explain this trend. What types of electron configurations are more reactive than others. Review how to write electron configurations. Review the electron configurations of each of the transition metals. Transition metal characteristics They are good conductors Have high melting/ boiling points. [exception Mg, which is a liquid at room temperature] The melting points and boiling points remain almost constant throughout the transition metals They are good alloys Atomic radii decrease as you move from left to right across a period Why? Because as you add more protons and more electrons, the
