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: -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-3: -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. For example, carbon-14 is a radioactive isotope of carbon that has six protons and eight neutrons in its nucleus.
Detailed explanation-4: -We can therefore see that for a neutral atom the number of protons is equivalent to the number of electrons. So, a neutral atom with six electrons will contain six protons in its nucleus.
