Two common quarks are called up with a charge of 23 and down with a charge of -13 protons are made up of 3 quarks How many of each quark would make a proton?
The proton has two up (electrical charge +1/3) quarks and one down (electrical charge -1/3) quark.
It is not currently confirmed whether quarks are made up of any smaller particles, but a theoretically suggested particle is Rishon.
two down quarks and one up
If protons are positive and are made of two up quarks and one down quark why do neutrons have no charge but are made of two down quarks and one up quark?
The reason that protons are positive and neutrons have no charge is owed to the fact that quarks, which make up these particles, do not have integral charge. The charge of an …up quark is +2/3, and the charge of a down quark is -1/3. When the charges of the quarks are added for the particles, we get the following: Proton = up quark + up quark + down quark = 2/3 + 2/3 - 1/3 = 4/3 - 1/3 = 3/3 = +1 Neutron = up quark + down quark + down quark = 2/3 - 1/3 - 1/3 = 2/3 - 2/3 = 0 (zero)
A neutron has one up quark, and two down quarks.
The two are related, yes, but technically it would be more accurate to say it the other way around: "Neutrons are heavier than protons because down quarks are heavier than …up quarks" Neutrons are composed of an up quark and two down quarks (udd). Protons are composed of two up quarks and one down quark (uud), so the difference in mass between a proton and neutron is (roughly) the same as the difference in mass between the neutron's down quark and the proton's matching up quark. Because a down quark is heavier than an up quark, it is also possible for a down quark to decay into an up quark (releasing an electron in the process). This is how beta radiation occurs in atomic nuclei. One of the neutrons' down quarks decays into an up quark, changing that neutron into a proton, and releasing an electron (as radiation), so another way to look at it would be that a down quark is an up quark that has an electron trapped inside it (the mass of the electron, plus the energy required to "trap" it there, is what makes the down quark heavier).
There are two up quarks and one down quark in a proton.
electron has no quarks. both electrons and quarks are fundamental particles and are composed only of themselves.
You get a neutron! down+down+up = neutron up+up+down= proton
Neutrons have a magnetic dipole moment due to the motion of their internal charged structure (quarks). However, there is no evidence yet of an Electric dipole moment. The …existence of an electric dipole would violate parity. Theoretically, there is more to the neutron (and all hadrons) than just 3 quarks. There are also the gluons and a 'sea' of valance quarks popping in and out of existence. Interestingly, if you sum up the masses of the up and down quarks in a neutron (2 down, 1 up) you don't get anywhere near the measured mass of the neutron itself. The gluons holding the quarks together are individually massless. However, their binding energy is what makes up the majority of the mass of the neutron (E = mc^2). A bit off topic, but it shows that there's more going on in the neutron than the simple 3 quark diagrams shown in many text books.
A proton is made up of two up quarks and one down quark.
Proton: 2 up, 1 down. Neutron: 1 up, 2 down.
Why do protons and electrons combine to form neutrons in a neutron star if protons are made of two up quarks and a down quark electrons aren't made of quarks and neutrons are made of two down quarks a?
Actually 'an' up quark. The weak nuclear force permits an interaction between an upquark and an electron that converts the up quark to a down quarkand the electron ceases to… exist, also an interaction between adown quark and a positron that converts the down quark to an upquark and the positron ceases to exist. There are also weak nuclearforce interactions that change quark types by emitting electrons orpositrons. Both the absorption and emission interactions describedabove are referred to as Beta Decay Processes . All BetaDecay Processes also involve emission of an electron neutrino or anelectron antineutrino (the lightest known particle having a nonzeromass and a particle that has almost no interaction at all withother matter).
