Neutrons are slightly heavier then protons. But not hugely so, together they are classed as nucleons.
If neutrons are free ie they are not bound to a proton they will decay. The neutron will split into a proton, an electon an an antineutrino.
Now to really mess with your mind it is possible to use that information to figure out the ratio of neutrons to protons in the universe.
I tried but he doesn't pick up the phone for some reason. But protons have no mass. They sit in the core of an atom and keep electrons in check with magnitism, plus and minus, atoms can be stable or unstable depending on the amount and the number of spheres of electrons. That is basic chemistry, atoms can merge and form molecules
Protons were discovered by Ernest Rutherford - a home schooled New Zealander.
They have a mass of 1.6726 x 10^-27 kg each.
Neutrons 1.6749 x 10^-27 each.
So neutron is heavier but not by much.
Electrons are a mere 9.109 x 10^-31 kg
Electrons are to Protons what grams are to kg (~ three orders of magnitude)
Let me put it this way. If protons have no mass, the sun started out pretty much mass less and is slowly creating more mass. That would in turn make us slowly falling into the sun (not counting that a mass less sun wouldn't be able to keep any planets in the first place). I think Pape is correct and you mixed up photons and protons on the mass matter.
Photons has no mass, although they still do have momentum. With the Higgs particle confirmed, it means that photons doesn't interact with the Higgs particle, afaik.
Correct that the electron mass is negligable compared to a proton.

We are all aware that the senses can be deceived, the eyes fooled. But how can we be sure our senses are not being deceived at any particular time, or even all the time? Might I just be a brain in a tank somewhere, tricked all my life into believing in the events of this world by some insane computer? And does my life gain or lose meaning based on my reaction to such solipsism?

Not laughing at you. Just sad that school missed teaching you science.
Chemistry is about how atoms and molecules interact; psychology for molecules. It is a crossroads between biology and geology and it uses physics to describe the models of the atom and molecules.
Chemistry defines elements by the number of protons they have:
1 proton = hydrogen
2 protons = helium
3 protons = lithium
4 protons = beryllium
5 protons = boron
6 protons = carbon
7 protons = nitrogen
8 protons = oxygen
That's the first eight and most important to us as a large chunk of biology uses carbon, oxygen, nitrogen and hydrogen.
Oil is essentially different combinations of Carbon and Hydrogen. Whilst alcohol is composed of carbon, hydrogen and oxygen.
