How many carbon isotopes exist

WebAtoms are made up of protons and neutrons located within the nucleus, with electrons in orbitals surrounding the nucleus. Protons and neutrons have approximately the same mass, about 1.67 × 10 -24 grams. Scientists arbitrarily define this amount of mass as one atomic mass unit (amu) or one Dalton, as shown in Table 2.2. WebJul 4, 2024 · The element carbon (C) has an atomic number of 6, which means that all neutral carbon atoms contain 6 protons and 6 electrons. In a typical sample of carbon-containing material, 98.89% of the carbon atoms also contain 6 neutrons, so each has a mass number of 12.
