elementary particles are generally divided into two groups: Hadrons, which are made up of quarks (three for baryons (ie. protons and neutrons), and two for muons), and the second group called Leptons (ie. electrons and neutrinos). there are also the force carrying particles: gluons (strong force), gravitons (gravity), W-bosons (weak force), and photons (electro-magnetivity) though as far as i am aware only photons have been observed and the rest are only theoretical.
What else can I help you with?
How many different quarks are there in Chemistry?
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.
Can subatomic particles be further subdivided?
SOME sub-atomic particles will decay into other particles. For example, a neutron will spontaneously change into a proton, an electron, and a neutrino.
Why quarks do not exist in free state?
Actually quarks can exist freely.
What subatomic particles are made of quarks?
Protons and neutrons contain quarks.
Who discovered down quarks?
Quarks were theorized in 1964 and experiementally verified in 1968. To say "invented" would be a misnomer. This next part is a direct quote from the Wikipedia article titled "Quark" [ http://en.wikipedia.org/wiki/Quarks ]: The quark model was independently proposed by physicists Murray Gell-Mann and George Zweigin 1964. There was little evidence for this model until 1968, when electron-proton scattering experiments indicated that the electrons were scattering off three point-like constituents inside the proton. All six flavors of quark have been observed, following the discovery of the top quark at Fermilab in 1995.
How is an electron made?
quarks
What is the role of quarks in an electron's structure?
Quarks are fundamental particles that make up protons and neutrons, which are in turn components of an atom. Quarks play a crucial role in the structure of an electron by interacting with other particles to form the overall structure of an atom. In an electron, quarks are not directly involved, as electrons are considered elementary particles and do not contain quarks.
How many quarks in electron?
The electron is considered to be an elementary particle and not composed of other particles, so there are no quarks in an electron. Particles composed of quarks are called Hadrons, the best-known being the Proton and the Neutron. The electron, on the other hand, is a Lepton.
Does electron has up or down quarks?
Electrons do not contain quarks. Quarks are fundamental particles that make up protons and neutrons in the nucleus of an atom, while electrons are a different type of fundamental particle with no quark composition.
How does quarks theory compensate spliting of neutron into electron and proton?
Supposedly one of the down quarks of the neutron becomes an up; thus the neutron becomes a proton and an electron (and a neutrino) are emitted.
What is inside of a proton?
There are three quarks: 2 up quarks and 1 down quark.
What is smaller then an atom?
Electrons for one, and protons and neutrons are composed of quarks
Why electron is lightest subatomic particle?
Out of electrons, protons, and neutrons, neutrons are the heaviest subatomic particle, with a mass of about 1838 times that of the electron. (If you are asking about electrons, up quarks, and down quarks, then electrons still aren't the heaviest Down quarks are the heaviest, with almost 10 times the mass of an electron.)
What is the smallest part of one atom?
As far as we know the electron. quarks
A particle in a atom that has a negative charge is a?
Electrons and down quarks have negative charge, as do strange and bottom quarks, along with muons and taus.
What particles are found in the electron and a neutron?
The electron is an elementary particle; it contains no other particles. Neutrons are composed of quarks.
What composes a neutron?
A neutron is made of 3 quarks, namely an up quark and two down quarks. It is this composition of quarks that cause it to have zero charge. (An up quark has a charge of 2/3 and down quarks have a charge of -1/3 - thus 2/3 + (-1/3 *2) = 0) A free neutron (that is one that is not bound in a nucleus) will become a proton, an electron and an electron-neutrino. This happens through the weak force (it acts on a down quark, turning into an up). This does not mean a neutron contains an electron. It does not. Yes, an electron appears when a neutron decays, but that electron does not exist in the neutron as an electron, but it does not.
