Web6 de nov. de 2024 · The number is the atomic mass. Subtract the atomic number of the element from the atomic mass of the isotope, and the result is the number of neutrons in the nucleus of that isotope. In the case of C-14, the atomic number of carbon is 6, so there must be 8 neutrons in the nucleus. That's two more than the more common, balanced … There are three naturally occurring isotopes of carbon on Earth: carbon-12 ( 12. C ), which makes up 99% of all carbon on Earth; carbon-13 ( 13.
