Questions & Step-by-Step Solutions

Which of the following transition metals can exhibit a +7 oxidation state?
Correct Answer: Manganese
  • Step 1: Understand what oxidation states are. Oxidation states indicate the charge of an atom in a compound.
  • Step 2: Identify transition metals. Transition metals are elements found in the d-block of the periodic table.
  • Step 3: Look for transition metals that can have a +7 oxidation state. This means they can lose 7 electrons.
  • Step 4: Check manganese (Mn). Manganese is a transition metal.
  • Step 5: Find an example of manganese in a +7 oxidation state. The permanganate ion (MnO4-) shows manganese with a +7 charge.
  • Step 6: Conclude that manganese is the transition metal that can exhibit a +7 oxidation state.
