Question 1
What oxidation state(s) is(are) exhibited by all first row transition elements except scandium?
◦ +2 and +3
◦ +2
◦ +3
◦ +2, +3 and +4
Question 2
What statement is most inconsistent with the chemistry of transition elements?
◦ Bromide, chloride and iodide stabilize the higher oxidation states of the transition elements.
◦ The stability of the higher oxidation states increases down a periodic group.
◦ Ions that have transition metal in their highest oxidation state tend to be good oxidizing agents.
◦ Early transition metal ions with the metal in its lowest oxidation state are good reducing agents.
