Protons and Neutrons are made of "quarks"
Up quarks have a 2/3 positive charge.
Down quarks have a 1/3 negative charge.
So, Protons are made of 2 up quarks and 1 down quark, and neutrons are made of 2 down quarks and 1 up quark.
Protons become neutrons when one of the up quarks is converted to a down quark and all other kinds of crap happens with release of energy and virtual particles.
There are 24 elementary feminons (or however you spell it) and additional bosons like photons and etc.
There are 6 quarks, 6 antiquarks, 6 leptons, and 6 antileptons.
An electron is a lepton.
A hadron is a composition of quarks.
A baryon is a hadron of three quarks.
Therefore protons and neutrons are baryons.
The nuclious of the atom is held together by the strong residentual force wich has to do with a color charge (not litteral colors) between quarks.
Quarks cannot exist by themselves. If you pull quarks away you will wind up creating a structure of 1 matter quark and one antimatter quark. These are called me somethings (I forget lol)
Shall I go on? I know ALOT about quantam physics, and I mean ALOT. Like how electrons jump around losing and gaining quantams of energy and all that good crap. I could go on forever explaining it all.
Bosons are particles that are transfered between femions which trasmit force. For example: The electromagnetic force is mediated by the photon as someone said (but I forgot who) before I replied.
Should I continue?
