Compared to the electron, how much heavier is the proton?
612067
The electron is 511KeV and a proton is 938 MeV. This makes the proton 1836 times as massive.

The volume of an atom is actually determined by the electrons.  An atom is composed of protons and neutrons in the nucleus and electrons in a cloud around the nucleus.  The nucleus does contribute nearly 100% of the mass of an atom but very little volume.  Electrons weigh basically nothing but are so far away from the nucleus that the volume of the nucleus is negligible.  To relate to something you may understand...if an atom's nucleus was placed at the fifty yard line in a football stadium the electron cloud would be up at the highest levels of the seating.

8 protons, 8 neutrons, 10 electrons

Protons and Neutrons can be divided into quarks, but electrons are not divisble as far as we know.

Well, as far as scale, it's easier to think of a proton as grape in the middle of a football field, an electron would be in the endzone. As far as strength compared to gravity...its about 10^36 times as strong. So if you weighed 150 lbs, and you were converted to an "electron-thingy", you would wiegh 150,000,000,000, 000,000,000,000,000, 000,000,000,000 lbs.

None of these particles. The mass of the proton and neutron are approximately 1 AMU, and the mass of an electron is approximately 1/1840 of that. So the electron mass is approximately 0.00054 AMU, not 0.000006 AMU .

Neutron, proton, and electron... though there are other sub-atomic particles making up these basic three.

The electron has smaller mass than any of the known quarks, and of course smaller than the proton or neutron.  Search the rest mass of up and down quarks against the .5 MeV of the electron.  You'll get estimates on the order of several hundred MeV.  I've taken "Smaller" here to mean mass, since the standard theory of particle physics assumes electrons and quarks to be pointlike and therefore both have no volume.

An ion differs from the original element in terms of the number of electrons.\n\nThe mass of an electron is about 1/1836 of a proton or a neutron.\n\nTherefore there would be a tiny difference in atomic mass, however in most cases it's fairly negligable.

26 electrons. If it's an electrically neutral atom, then the number of protons must equal the number of electrons.

Nope, the magnetic information (not electronic!) doesn't weigh anything, it's all related to the orientation of the "magnetic moment" (up or down) of the atoms i.e. the way atoms are turning (to make it simple). they're not heavier if they turn in one sense than if they does in the other

The atomic number (the big number in the middle or on top of the square) represents the number of protons in the atom, but since an atom is by definition neutral, the number of electrons is the same.  For an ion, you would take the atomic number and subtract the charge, so for instance, carbon (atomic # 12) with a +1 charge would have 11 electrons.

atoms of positive charge are lighter than negative.

92 protons and 92 electrons\nIsotopes have a different number of electrons

Well, a proton is not an elementary particle.  And the electron is the smallest lepton.  However, an elementary muon will decay to an electron and neutrino when passing from space into an atmosphere

The mass of protons and neutrons are nearly identical, the mass of an electron is about 1/1840th the mass of a proton, thus it is negligible, so you can't really tell its there.

The mass of the electron has been measured to an accuracy of 0.17 parts per million.  That's consistent with all electrons having the same mass, but not enough to rule out the possibility of more than one mass value where all are within the accuracy limits of our measurements.  The proton mass is known to the same accuracy.\n\nThe charge of the electron has been measured to 85 parts per billion.  No measurement has found a difference in magnitude between the electron and proton charge.\n\nTo answer the question, I would try to think of experiments whose outcome would be different if the mass or charge differed.  I would also run lots of simulations with varying assumptions for those values.  Quantum effects make it extremely difficult to measure the results of such experiments.
