Expert Answer:
All elements are made up of more than one isotope.
Isotopes are atoms of the same element with same atomic number but different atomic masses.
Carbon is no exception and is made up of isotopes with masses 12, 13 and 14 written as 126C, 136C, 146C.
Similarly, uranium with atomic number 92 has isotopes 234U , 235U and 238U.
