I don't understand Chemistry

[HoreTore]

That is basic chemistry, atoms can merge and form molecules

That is indeed both basic and correct, but protons still do have mass.

[Philippus Flavius Homovallumus]

That is indeed both basic and correct, but protons still do have mass.

Protons have mass - electrons and photons have negligible mass.

[HoreTore]

Protons have mass - electrons and photons have negligible mass.

Photons are the protestants of the world of chemistry.

[Papewaio]

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)
