B. protons, but different numbers of neutrons. All atoms of an element have the same number of protons and electrons (in the neutral state). Matt B. b. are isotopes of the same element. For instance, a neutral sodium atom (say, from a chunk of sodium metal) reacts with water much more violently than an ionized sodium atom (say, from a bit of salt). For example, all carbon atoms have six protons, and most have six neutrons as well.
