Carbon 14 has the same
Did you know?
WebCarbon occurs naturally in three isotopes: carbon 12, which has 6 neutrons (plus 6 protons equals 12), carbon 13, which has 7 neutrons, and carbon 14, which has 8 neutrons. Every element has its own number of isotopes. The addition of even one neutron can dramatically change an isotope’s properties.
