Question

How many nucleons does carbon have?

Answer 1

Hint :Carbon is a chemical element with the atomic number 6 and the symbol C. It is non-metallic and tetravalent, which means it can form covalent chemical bonds with four electrons. It is in Periodic Group 14 of the periodic table. Carbon accounts for only about 0.025 percent of the Earth's crust.

Complete Step By Step Answer:
A nucleon is a proton or a neutron considered in its role as a component of an atomic nucleus in chemistry and physics. The number of nucleons in a nucleus determines the mass number of an isotope. Nucleons were thought to be elementary particles, not made up of smaller parts, until the 1960s.
Nucleons exist at the intersection of particle physics and nuclear physics. Particle physics, particularly quantum chromodynamics, provides the fundamental equations that explain quark and strong interaction properties. These equations quantitatively explain how quarks can bind together to form protons and neutrons (and all the other hadrons).
A carbon atom is made up of six protons, six electrons, and six neutrons. The number of protons and electrons for a given element is fixed and always the same, but different numbers of neutrons can be found in the nucleus. Some hydrogen atoms in nature, for example, have one neutron.
There are actually 3 types of carbon:
 $ {}^{12}C $ : 12 nucleons : 6 protons and 6 neutrons
 $ {}^{13}C $ : 13 nucleons : 6 protons and 7 neutrons
 $ {}^{14}C $ : 14 nucleons : 6 protons and 8 neutrons.

Note :
These fundamental equations become too difficult to solve directly when multiple nucleons are assembled into an atomic nucleus (nuclide) (see lattice QCD). Nuclides are instead studied within the context of nuclear physics, which investigates nucleons and their interactions using approximations and models such as the nuclear shell model. These models are capable of explaining nuclide properties such as, for example, whether or not a particular nuclide undergoes radioactive decay.
