Detailed explanation-1: -It has an atomic number of 6. That means a carbon atom has 6 protons, 6 neutrons, and 6 electrons.
Detailed explanation-2: -In the case of carbon, it has six protons in the nucleus of its atom. Hence, the atomic number of carbon is six.
Detailed explanation-3: -Every carbon atom has six protons, and the majority of carbon atoms have six neutrons. A carbon-12 atom has 6 protons (6P) and 6 neutrons (6N). But some types of carbon have more than six neutrons. We call forms of elements that have a different number of neutrons, isotopes.
Detailed explanation-4: -Carbon-12 is of particular importance in its use as the standard from which atomic masses of all nuclides are measured, thus, its atomic mass is exactly 12 daltons by definition. Carbon-12 is composed of 6 protons, 6 neutrons, and 6 electrons.
