How many neutrons are in an atom of carbon with a mass number of 14?


help please...

    Carbon has an atomic number of 6, which means it contains 6 electrons. To find the number of neutrons, just subtract the atomic number from the mass number. So 14-6 = 8.

    There are 8 neutrons in an atom of carbon with a mass number of 14.

    Eight is correct for the number of neutrons. Carbon-14 is an important isotope used for radioactive dating of carbon-containing organic matter. Its half life is 5568 years.
