Final answer:
Transition elements are the elements found in Groups 3-12 of the periodic table. They are metals that display typical metallic properties. Examples include manganese, titanium, and copper.
Step-by-step explanation:
Transition elements are the elements found in Groups 3-12 of the periodic table. They are called transition elements because their d sublevel, which is in the process of being filled, is in a lower principal energy level than the s sublevel. These elements are all metals and display typical metallic properties. Examples of transition elements include manganese (Mn), titanium (Ti), and copper (Cu).
