What quarks make up a neutron?

Answer 1

Quarks are building blocks for subatomic particles. They are considered to be fundamental particles, and are thus not made up of other particles. Quarks bind together with gluons to make composite particles called hadrons. The most common examples of a hadron are neutrons and protons. Quarks are assigned names called flavors: up, down, strange, charm, top and bottom. Each flavor can be positive or negative. Quarks have been observed as resultants in collisions in particle accelerators, which leads to another characteristic of these fundamental particles: they cannot exist by themselves.

Quarks do not exist in isolation, so nearly everything we know about them is deduced from the examination of other particles and particle reactions. Most of this work is done in high energy physics laboratores where particle accelerators are used in experiments. It is thought that at the very beginning of the universe (the Big Bang) it may be that the extremely hot conditions allowed for the existence of unbound quarks in a quark-gluon plasma.

There is a lot more to learn about these curious particles, and an investigator can use the link below to do further reading and to gather more facts. Knowing a thing or two about quarks is essential for anyone who wishes to grasp the fundamentals of the Standard Model. This platform (the Standard Model) is used by physicists to describe the way the strong and weak interactions and the electromagnetic force mediate the way subatomic particles interact.

Answer 2

A "neutron quark" could be said to be one of the three quarks that make up the neutron. There are two "down" quarks and an "up" quark in the neutron. Someone with a bit of extended knowledge concerning particle physics might find the term "neutron quark" a bit uncomfortable. It might be like saying a "sodium neutron" or a "tungsten proton" or something along those lines. It may be better to say "one of the quarks that make up a neutron" or the like. A nice drawing of the neutron showing its quarks can be found using the link to the Wikipedia article. Call it a "family portrait" if you like....

Answer 3

Any baryon by definition contains three quarks (or three antiquarks). The neutron, and proton, by the way, are both baryons, and the neutron contains two down quarks and one up quark.

Answer 4

A neutron has 3 valence quarks. An up quark, and two down quarks. An up quark has a charge of 2/3 and a down quark has a charge of -1/3.
Since 2/3 - 1/3 - 1/3 = 0, neutrons have a neutral charge.


Besides valence quarks, supposedly a hadron can contain an infinite sea of quarks that don't affect the properties of the hadron.

Answer 5

there are 3 quarks in a neutron and three quarks in a proton.

Answer 6

Two down quarks and an up quark. A down quark has a charge of -1/3 while an up quark has a charge of 2/3. 2/3 - 1/3 - 1/3 = 0, which is why a neutron has a neutral charge

Answer 7

two down quarks and one up
