Answer» For example, if you have a carbon-11 atom, you can tell that the ATOMIC weight is approximately 11, and you subtract the amount of PROTONS in it. There are 6 protons in a carbon atom so you subtract 6 from 11, which gives you 5. That MEANS that you have 5 NEUTRONS in that atom. The same goes for ions. |
