WebAn atom always has a equal number of protons and electrons so it has no over all charge (0). Atoms of the same element have the same number of protons - e.g. ... out by doing the mass minus the atomic number (big number minus small number). E.g. Carbon has a mass of 12 and an atomic number of 6. Therefore it has: • 6 protons Web• Each atom has a charged substructure consisting of a nucleus, which is made of protons and neutrons, surrounded by electrons. (HS-PS1-1) • The periodic table orders elements horizontally by the number of protons in the atom’s nucleus and places those with similar chemical properties in columns.
