They have the same number of protons, which determines the element&#8217;s atomic number, but different numbers of neutrons, which determines the element&#8217;s mass number. For example, carbon-12 has 6 protons and 6 neutrons, while carbon-14 has 6 protons and 8 neutrons.<\/p>\n<p>Protons and neutrons are both found in the nucleus of an atom.
