Carbon isotopes name
WebFeb 4, 2024 · Carbon 12 and Carbon 14 are both isotopes of carbon, one with 6 neutrons and one with 8 neutrons (both with 6 protons). Carbon-12 is a stable isotope, while carbon-14 is a radioactive isotope (radioisotope). Uranium-235 and uranium-238 occur naturally in the Earth's crust. Both have long half-lives. Uranium-234 forms as a decay product.
