Wich subatomic particle will you add or remove to change the charge of the atom A) Electrons or neutrons B) Neautrons or protons C) Electrons or protons

B. Neutrons or Protons Adding or removing protons from the nucleus changes the charge of the nucleus and changes that atom's atomic number. For example, adding a proton to the nucleus of an atom of hydrogen creates an atom of helium. (Actually, a few neutrons have to be added as well to make the new nucleus stable, but the end result is still helium.)
