Subatomic Particles

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.
