Protons and neutrons have approximately the same mass, about 1.67 10 24 grams. Often, the number of protons and electrons is not the same, so the atom carries a net positive or negative charge. 27 d.). The atomic mass is carried by the atomic nucleus, which occupies only about 10-12of the total volume of the atom or less, but it contains all the positive charge and at least 99.95% of the total mass of the atom. Protons are the positively charged particles within an atom. An anion carries a negative charge and has more electrons than protons. - The ATP synthesis is connected with the production of the proton gradient in the membrane of the thylakoid, according to chemical hypotheses.
