Which transition metal is known for forming a variety of oxidation states and colored compounds?

Which transition metal is known for forming a variety of oxidation states and colored compounds?

Step 1: Understand what transition metals are. They are elements found in the middle of the periodic table.
Step 2: Learn that transition metals can lose different numbers of electrons, which gives them different oxidation states.
Step 3: Identify that oxidation states are the charges that an atom can have when it forms compounds.
Step 4: Recognize that some transition metals, like copper, can have more than one oxidation state. For copper, these are +1 and +2.
Step 5: Discover that transition metals often form colored compounds. For example, copper(II) sulfate is blue.
Step 6: Conclude that copper is a transition metal known for forming various oxidation states and colored compounds.
