If carbon has an atomic number of 6, how can its atomic weight be 12.011 g/mol?
- The weight depends on the number of nucleons, which is usually 12 and rarely 13 in natural abundance.
- The weight is always twice the atomic number, plus a contribution from the binding energy of the atoms.
- The weight is the weight of the most common isotope found in nature, which has a weight a bit more than 12 g/mol.
- In reality, physical quantities will never be exactly the theoretical values.
- Carbon always appears in nature as a molecule of 2 carbon atoms hence the atomic weight is double the atomic number.
