* Molecule: A molecule is formed when two or more atoms bond together.
* Atom: An atom is the smallest unit of an element that retains the chemical properties of that element.
Therefore, a molecule is inherently made up of multiple atoms, not a single atom.
It seems you might be thinking of monatomic molecules. These are molecules made up of only one atom, like:
* Noble gases (Helium, Neon, Argon, etc.) exist as individual atoms, making them monatomic molecules.
