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: -Carbon-12: with 6 protons and 6 neutrons and an atomic mass of 12.
Detailed explanation-3: -The most common form of Carbon has 6 protons, 6 neutrons and 6 electrons. Nitrogen has 7 protons, 7 neutrons and 7 electrons. Heavier atoms tend to have more neutrons than protons, but the number of electrons in an atom is always equal to the number of protons. So an atom as a whole is electrically neutral.
Detailed explanation-4: -Neutral carbon-12 (or any carbon atom) has 6 electrons with a total negative charge of 6e-orbiting a nucleus with a total positive charge of 6e+, so that the total net charge is zero. The nucleus is made up of 6 protons, each with a positive charge of e+, and 6 neutrons, each with zero charge.
Detailed explanation-5: -Carbon atoms with 7 neutrons have an atomic mass of 13 (6 protons + 7 neutrons = 13). These atoms are the isotope called carbon-13.
