The hydrogen atom as a whole is electrically neutral so it needs to have equal number of protons and electrons. It consists of an electron, with a negative electrical charge, orbiting a proton, which carries a positive charge. The proton forms the central nucleus of the atom. The equal and opposite charges of the proton and the orbiting electron produce an electrical attraction that binds them together within the atom.
