Atoms are neutral, meaning they have the same amount of protons and electrons (positives and negatives).
Isotopes are different versions of a element. Carbon-12 and Carbon-14 are isotopes. Both atoms would have six protons and six electrons but the Carbon-14 is heavier because it has two extra neutrons. The number of neutrons is usually close to or larger than the number of protons in an atom.
Ions are atoms that have lost or gained electrons so that they have a charge.
Watch the video below to see examples of how protons, neutrons, and electrons are represented on atomic symbols.
