Here's why:
* Atoms are the fundamental building blocks of all matter. They are the smallest unit of an element that retains the chemical properties of that element.
* Copper, like all elements, is made up of copper atoms. These atoms are bonded together in a specific arrangement to form the solid copper material we know.
* Smaller parts than atoms would be subatomic particles (like protons, neutrons, and electrons), which are not considered to be copper itself.
