Question

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.

Explanation:

When uranium breaks under high - energy conditions to form plutonium, a nuclear reaction occurs. In nuclear reactions, new elements (atoms) are formed. Plutonium is an element different from uranium. Matter is conserved in such processes, and different elements have different properties.

Answer:

It must be a different kind of atom.
