Uranium is a type of atom. In special circumstances that usually involve high amounts of energy, uranium can be broken. When this occurs, different pieces of the original atom remain, including a substance called plutonium.

Which statement most likely describes plutonium?

• It will still be uranium, just smaller pieces of uranium.

• It must no longer be a form of matter.

• It must be a different kind of atom.

• It will be different than, but have the same properties as, uranium.
