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: -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-4: -Carbon atoms with 7 neutrons have an atomic mass of 13 (6 protons + 7 neutrons = 13). These atoms are the isotope called carbon-13.
Detailed explanation-5: -A carbon-14 atom has 6 protons, 8 neutrons, and 6 electrons, so its mass number is 14 and its atomic number is 6.
