Detailed explanation-1: -Carbon occurs naturally in three isotopes: carbon 12, which has 6 neutrons (plus 6 protons equals 12), carbon 13, which has 7 neutrons, and carbon 14, which has 8 neutrons.
Detailed explanation-2: -Isotopes are forms of the same element with equal numbers of protons but different numbers of neutrons. For example, both carbon-12 and carbon-14 have 6 protons.
Detailed explanation-3: -As such, for N-14, there are 7 neutrons. On the other hand, a carbon atom will always have 6 protons regardless of the identity of the isotope. As such, C-14 has 8 neutrons. Therefore, N-14 has more protons and fewer neutrons than C-14.
Detailed explanation-4: -Isotopes are atoms of the same element that have different numbers of neutrons but the same number of protons and electrons. The difference in the number of neutrons between the various isotopes of an element means that the various isotopes have different masses.
Detailed explanation-5: -THE DIFFERENT ATOMIC WEIGHT VARIANTS OF AN ELEMENT ARE CALLED THE ISOTOPES OF THAT ELEMENT. (For example C12, C13, and C14 are all isotopes of carbon, all have 6 protons but each has a different number of neutrons).
