Показать описание

Isotopes are different atoms of the same element, which have the same number of protons and a different number of neutrons. The relative atomic mass of an element is the average relative mass of all the isotopes in the element. The average mass of an atom is compared against the mass of an atom of carbon-12, which is given a mass of exactly 12.

What's the difference between atomic mass and relative atomic mass?

but when finding the RAM for carbon, won't the average then be 13 since 12+13+14/3 is 13?
