None of the above

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: -When protons equal electrons the atom is neutral. When protons are greater than neutrons the atom is a positive charge or cation. When the protons are less than the electrons the atom is a negative charge or anion. For this example the Carbon atom has 6 protons and 6 electrons making it neutral.
Detailed explanation-5: -Since atoms are neutral, the number of electrons in an atom will be the same as the number of protons. Therefore, since this element has an atomic number of 6, each atom of this element will have 6 protons and 6 electrons.
