It seems that some people are interested in certain scientific topics, some are not. So, even if they hear about protons, neutrons, quarks, etc. in school, some people will not make an effort to learn more about the subject, and will soon forget it.
As far as we know the electron. quarks
The count of quarks in an atom of molybdenum would depend on the nuclide's mass number (A), or in other words, on which isotope. 3 * A = (quark count) since both neutrons and protons have 3 quarks each. The lowest we know about (Mo-83) would have 249 quarks, the highest (Mo-115) would have 345. Molybdenum-98 is the commonest isotope with (3 * 98) quarks.
In an atom, the neutrons and protons are made up of up quarks and down quarks. Strange quarks, charms quarks, top quarks, and bottom quarks also exist, but do not play as much of a role in the structure of an atom.
Hadrons are composed of 3 quarks. Protons and neutrons are hadrons. The 2 types of quarks used in this instance are up quarks and down quarks. Yes, there are quarks in a nucleus.
No, they are now solid fact. Quarks are the fundamental particles which make up the protons and neutons of everything around us, as well as some other crazy particles such as the Higgs boson. There are some bosons (things made up of quarks) which are merely theoretical; we know they muct exist but have not yet found one, but quarks are definitely NOT fictional
Quarks and anti-quarks
There are six quarks, the up, down, charm, strange, top, and bottom quarks.
Up quarks Down quarks Bottom quarks Top Quarks Charm quarks Strange Quarks and then there were leptons... simple- 8 protons 8 electrons 8 Neutrons and if you're dumb and you mean what is in air, then why don't you learn how to google
The quarks came when at the start of the universe, the energy was converted into matter. This matter is the quarks. The quarks join to form the element hydrogen, which fuses to form other elements.
Protons and neutrons are composite particles make up of up and down quarks. There are two up quarks and one down quark in a proton, and two down quarks and an up quark in a neutron.
Up quarks and down quarks are in protons and neutrons.
Up quarks and down quarks are in protons and neutrons.
