Given what we know, we can confirm that relative atomic mass is calculated by comparing the particles to the atomic mass of a carbon-12 atom.
Why compare to carbon-12?
- Carbon is a very common element.
- It was been studied greatly, telling us a great deal about the atom.
- It contains 6 protons and 6 neutrons.
- This makes it very stable and the standard for comparison.
Therefore, given its abundant nature and the fact that it has been extensively studied, we can confirm that a carbon 12 atom has exactly 6 protons and 6 neutrons, making it very stable and the standard to which other atoms are compared.
