What are quark combination of proton and neutron?
P=UUD (two up, one down) N=DDU (two down, one up) Down quarks are charge -1/3 relative to a proton and up quarks are charge +2/3 relative to a proton.
What is antiquarks?
The antiparticle of a quark is called as an anti quark. Which has the same mass but other properties are opposite. Example - Their charge. From the family(group) of quark Up has +2/3 whereas anti-up has -2/3. Quark is a matter ( particle ) whereas an anti quark ( antiparticle ) is antimatter
Do neutrons have net charge?
No. Neutrons do not have a net charge. They are comprised of two down quarks, each with a charge of -1/3 and one up quark, with a charge of +2/3. These cancel out, for a net charge of zero.Constrast this with the proton, with one down quark, -1/3, and two up quarks, +2/3. for a net charge of +1.
Which combination of quarks can produce a neutral baryon?
Ans 1 Any with a combination of an up, charm, or top quark, and a combination of two down, strange, or bottom quarks. ([(+2)+(-1)+(-1)=(0)]). Ans 2 Two down quarks and an up quark. This combination is a neutron. A down quark has a charge of -1/3 and an up quark a charge of +2/3
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.
What is relative in 'relative charge'?
Relative means that it is compared to something. For example, the relative charge of a proton is +1 and it is relative to that proton. The relative charge of an electron is -1 relative to protons. That means it is exactly the same, but opposite. The relative charge of an up quark is +2/3, and that means that the charge of that quark is 2/3 of the charge of the proton. It depends what it is compared to.
What are quark combination of proton and neutron?
P=UUD (two up, one down) N=DDU (two down, one up) Down quarks are charge -1/3 relative to a proton and up quarks are charge +2/3 relative to a proton.
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)
What charge do the different subatomic particles have?
I suppose you are talking about electric charge (since there are others like color or hypercharge). Everything is in units of the elementary charge (i.e. ~1.6 * 10-19 C) The following particles have a charge of +2/3 Up Quark, Charm Quark, Top Quark The following particles have a charge of -1/3 Down Quark, Strange Quark, Bottom Quark The following particles have a charge of -1 Electron, Muon, Tau, Proton (but the Proton consists of two ups and one down quark), W- boson The following particles have a charge of +1 W+ boson The following particles have no charge: Electron Neutrino, Muon Neutrino, Tau Neutrino, Neutron (consists of two down and one up quark), Photon, Higgs (not found yet), Graviton (also not yet found), Z0 boson, gluon. There are also various other composite particles such as mesons, but those are far too numerous to list.
What is a charm quark?
A charm quark is an elementary particle with an electrical charge of +2⁄3 e. It's a second generation up-type quark and has a mass of about 1.5 GeV/c2.
What is antiquarks?
The antiparticle of a quark is called as an anti quark. Which has the same mass but other properties are opposite. Example - Their charge. From the family(group) of quark Up has +2/3 whereas anti-up has -2/3. Quark is a matter ( particle ) whereas an anti quark ( antiparticle ) is antimatter
How does the proton get the positive charge?
The proton is composed of three elementary particles called quarks. These quarks are influenced by the electromagnetic force and therefore have a charge. The quark makeup of one proton is 'uud', or 2 up quarks and one down quark. The charge of a proton is +1 e (as opposed to that of an electron; -1 e) The charge of an up quark is +2⁄3 e and that of a down quark is -1/3 e. Therefore you get +2⁄3 e + +2⁄3 e + -1/3 e which amounts to +1 e. The reason a neutron is neutral is for the same reason. It's composition is 'udd', or one up quark and two down. I won't actually write it out again, but when the charge of one up quark and two down is added the charge is 0 e
What are neutrons made up of?
Neutrons are made up of Down and Up quarks. Each neutron has one Up quark and two Down quarks. Each Up quark has a two third positive charge while each Down quark has a one third negative charge.
Do neutrons have net charge?
No. Neutrons do not have a net charge. They are comprised of two down quarks, each with a charge of -1/3 and one up quark, with a charge of +2/3. These cancel out, for a net charge of zero.Constrast this with the proton, with one down quark, -1/3, and two up quarks, +2/3. for a net charge of +1.
What atomic particles always carry a negative charge?
The electron, muon and tau; the down quark, the strange quark, the bottom quark; and the W boson.
What is the smaller portion of the proton?
The quark! A proton is made of two Up quarks and one Down quark. The Up quark has a charge +(2/3)*e and the Down quark has a charge -(1/3)*e; where 'e' is the elementary charge of the electron. Since we know that a proton has a net charge of +e it must mean that a proton is +(2/3)*e+(2/3)*e-(1/3)*e = +(4/3)*e-(1/3)*e = +(3/3)*e = +(1)*e = +e
Which combination of quarks can produce a neutral baryon?
Ans 1 Any with a combination of an up, charm, or top quark, and a combination of two down, strange, or bottom quarks. ([(+2)+(-1)+(-1)=(0)]). Ans 2 Two down quarks and an up quark. This combination is a neutron. A down quark has a charge of -1/3 and an up quark a charge of +2/3
