I don't understand Chemistry

[Ironside]

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

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.

Protons have mass - electrons and photons have negligible mass.

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.
