Two up and one down quarks combination is the Creation of a proton.
There are quarks in the nucleus of an atom, but they are found there because quarks make up protons and neutrons which make up atomic nuclei. They (quarks) do not have "individual identities" in the nucleus of an atom, but are elementary particles that are the building blocks of composite particles called hadrons. Quarks are never found in isolation anywhere.
Protons are made up of subatomic particles, called quarks. In a proton, there are three quarks: two up quarks, and one down quark (basically positive and negative quarks, but there is a fine difference between up and positive, and down and negative quarks, so down and up are used when referring to types of quarks). So, a proton isn't just a positively charged, solid particle - it is made up of smaller particles. Though, protons aren't broken down any further than quarks, because quarks are elementary particles. Elementary particles are particles that aren't made up of anything smaller than itself.
Protons and neutrons are made up of quarks, which are fundamental particles. The specific formula used to describe the composition of protons and neutrons is based on the concept of quantum chromodynamics (QCD), which involves three types of quarks: up, down, and strange. A proton consists of two up quarks and one down quark (uud), while a neutron is made of one up quark and two down quarks (udd). These quarks are held together by the strong force, mediated by particles called gluons.
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.
Proton therapy uses protons, which are positively charged subatomic particles found in the nucleus of an atom. Hydrogen atoms, which consist of a single proton in their nucleus, are commonly used as the source of protons in proton therapy.
Actually every proton has different size in different nucleus. But in general, Proton, 1x10-15 m or "a diameter of approximately one-millionth of a nanometer". The electron, the diameter is less than 1x10-18 m. Likewise, The diameter of an electron is less than 1/1000 the diameter of a proton.
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.
The quark comes with what is called a fractional charge. From a purely theorhetical standpoint, a flow of quarks could generate a magnetic field about their path of travel, and this might be used to generate electricity. But quarks, because they have a characteristic called color confinement, cannot exist freely in nature. The quark only exists inside a composite particle called a hadron, of which the proton and neutron are examples. Don't look for any "quark flow" like you would electron flow in what we normally consider electricity. It's something that isn't going to happen.
When speaking in the past tense.
Quarks have not been observed to exist separately - they are "confined" within larger particles such as protons and neutrons, that are made up of several quarks (3 each, in the case of protons and neutrons).
