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. The number of protons determines the element&#8217;s chemical properties, while the number of neutrons affects the atom&#8217;s stability. Isotopes of the same element have the same chemical properties, but they may have different physical properties. For example, carbon-12 is a stable isotope, while carbon-14 is radioactive.<\/p>\n<p>The other options are incorrect. Option B is incorrect because isotopes have the same number of protons, not neutrons. Option C is incorrect because isotopes have the same number of protons, not electrons. Option D is incorrect because isotopes have the same number of protons and neutrons, not nucleons.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>[amp_mcq option1=&#8221;the same number of
