what are all of the subatomic particles? what are they made of?

Question

what are ALL the subatomic particles, including ones scientists dont know much about, and the ones the textbooks dont bother to mention.

What are those particles (electrons, protons, neutrons, quarks, ect) made of?

are there alpha or beta subatomic particles?

Answer 1

Subatomic particles are protons and neutrons (or anything even smaller). They are made out of different varieties of quarks. Two up quarks and one down quark, with the help of a messenger particle called a "gluon" make a proton. Two down quarks and one up quark make a neutron. According to string theory, quarks are "strings," as are electrons, photons, and neutrinos. Strings are one dimensional threads of energy vibrating in 10 dimensions (11 if you count time).

An alpha particle is an ionized (no electron) hydrogen nucleus (proton) with a neutron attached. A beta particle is an ionized helium nucleus (2 protons, 2 neutrons). These particles moving at near light speed pack quite a punch.

Answer 2

Some day, those who study such things will find yet more particles. Even the spaces between the particles will prove to be made of 'something', and this 'something' will consist of more particles. The entire working theory may have to be discarded.

It sure is hard to be 'absolute' about anything. 'As far as we know' seems an appropriate choice of words.

Answer 3

They are elegtrical cgarges. Protons are positive charges. Electrons are negetive charges. Neutrons are neutral charges. The combination of these make up everything you see.

Answer 4

they are made of mass holding a charge. i believe their existence is largely theoretical, to explain the behaviour of matter (larger matter) and energy.
