There are many atoms in a sample of carbon, although there are many different particles in that atom.
Adfditional answer
You may actually be asking "Is carbon made of only one TYPE of atom?". Answer - they are all carbon atoms but there is more than one type of carbon atom. The different ypes are known as isotopes. Most elements have several isotopes. (Don't confuse an isotope with an allotrope, e.g. diamond is an allotrope of carbon but itself can be made of several isotopes of carbon)
