How many protons, neutrons and electrons can be found in an atom of carbon-12?
Carbons’s atomic number is 6 (from periodic table)
atomic number = number of protons → 6 proton
Atom of carbon has no charge
Already said 6 proton → 6 electrons
Electrons balance protons
Carbon-12 → number of particles in nucleus
Nucleus is only protons and neutrons
Already 6 protons → 6 neutrons
An atom of carbon-12 has 6 neutrons, 6 protons, and 6 electrons.
