Why are neutrons not electrified? Can you give us a brief introduction to quarks?

Because neutrons are composed of three quarks, the three quarks themselves have positive and negative properties, but because the respective charged charges of the quarks are unequal when combined, but the sum is zero, the overall apparent charge is neutral, that is, uncharged.

The charge value of a quark is a fraction – 1 3 times or +2 3 times the basic charge, depending on the taste. The charge of the upper, can, and top quarks (these three called "upper quarks") is +2 3, while the charge of lower, odd, and bottom quarks (these three are called "lower quarks") is 1 3. Antiquarks are the opposite of their corresponding quark charges; The charge of the upper antiquark is 2 3, while the charge of the lower antiquark is +1 3.

Protons are made up of two lower quarks with a charge of -1 3 and one upper quark with a charge of +2 3 with a total charge of 0

Neutrons are made up of one lower quark with a charge of -1 3 and two upper quarks with a charge of +2 3 for a total charge of +1

Quark: (just to say it simply).

Matter is made up of molecules, molecules are made up of atoms, atoms are made of electrons and nuclei, nuclei are made of protons and neutrons, and protons and neutrons are made of quarks. Quarks have quarks and antiquarks. Both quarks and antiquarks have 6 flavors, which are:

Upper quark, lower quark, odd quark, bright quark, bottom quark, top quark, each quark has three colors: red, yellow, green.

The neutron is made up of 2 lower quarks and 1 upper quark, the lower quark has a charge value of -1 3 and the upper quark is 2 3, so the sum is 0, so the neutron is not charged.

According to the quark model, quarks are fractionally charged, with each quark having a +2 3e or -1 3e charge (e is the proton charge unit).

A neutron consists of two lower quarks and one upper quark, and since the upper quark has a +2 3e charge and the lower quark has a -1 3e charge q=-1 3e*2+2 3e=0, the neutron is not charged.

A proton is composed of two upper quarks and one lower quark, and since the upper quark has a +2 3e charge, the lower quark has a -1 3e charge, and 2 3e*2-1 3e=e, the proton has a positive charge.

It's because neutrons are not charged that they are called neutrons.

Analysis: The proton charge is +e, so it is composed of 2 upper quarks and 1 lower quark. According to the title, three quarks must be located at the three vertices of an equilateral triangle. At this time, the electrostatic force between the upper quark and the upper quark should be.

fm=k=k ①

Substituting the data, fm=46 n, which is the repulsion. ②

The electrostatic force between the upper and lower quarks is fnd=k=k

Substituting the numerical value, we get FND=23 N, which is the attraction.

In the future, the first thing to ask is to make it clear, do you want to know what is the Coulomb force of the adjacent quark? According to the formula of Coulomb force f=q1q2 r2, the distance between the intake is roughly calculated. Don't think that the Coulomb force will be very large at such a small distance, in fact, at such a small distance, the main force is the strong interaction force, and here, the Coulomb force between quarks can be ignored compared to the strong interaction force.

Protons are charged because of quarks.

The reason why electronics with TV is because electronics itself is electricity.

The problem of electrons being charged is like a triangle.

The question of why the triangle is the same, because it has such a property itself, and thus there is no why. Let's start with "protons" and "electrons". Both protons and electrons are the elementary particles that make up matter.

Matter in the world, without exception, is made up of atoms, which in turn are made up of atomic nuclei.

and extranuclear electrons. The nucleus of an atom is made up of two substances, protons and neutrons.

The essence of electrons is a form of energy, and electrons have reached the point where they can no longer be decomposed, so naturally there is no question of what constitutes them. We all know that photons have wave-particle duality.

Is it true or false that electrons are also said to have wave-particle duality and are completely identical? According to scientific research, this statement is true to some extent. How did the "photon" come about, the photon did not exist in large quantities at the beginning of the universe, what was it before the universe?

The more reliable is the "universe **" theory. <

13.8 billion years ago, when all matter in the universe started with a singularity. After the singularity**, the present universe and everything were formed. In the early stages of the history of the formation of the universe, the entire universe was in a state of high temperature.

It develops in a rapidly expanding state, leaving behind a substance called "glow".

The great theory of the universe is accurate that this glow should develop in the form of microwaves, and it is in a visible state. As expected, scientists used the precision equipment of orbital detectors to accurately measure the possibility of the existence of cosmic microwaves, which provides a factual basis for the correctness of the big theory. <

Through the above facts and examples, we have a more systematic grasp of the question of how electrons and protons are created, and the history of the universe before and after its formation.

Protons are charged due to the gravitational pull of quarks, and electrons are charged because the movement between the charges causes the electrons to carry a negative charge.

Protons are charged due to quarks, whereas electrons are charged due to the fact that the electrons themselves are electric.

The electrification problem of electrons is like the question of why a triangle is a triangle because it has such a property so there is no why. Let me first understand "proton, jujube" and "electron". Both protons and electrons are the elementary particles that make up matter.

Everything in the world is no exception. They are all made up of atoms, which are made up of the nucleus and electrons outside the nucleus. The nucleus of an atom is made up of two substances, protons and neutrons. Stool liquid.

Because the electron is charged, it is it itself that has such a property, so there is no why.

Electricity"is not there, so-called"Electricity"is a definition of a special particle flow.

Lower quarks. The charge is (-1 orange chop 3) e, i.e. 1 3.

Negatively charged. Up quark.

With +(2 3)e, i.e. 2 3.

Positive charge. Protons are composed of two upper quarks and one lower quark under the tent, 2*(+2 3)-1 3=1, so the proton has one unit of positive charge.

The neutron consists of two lower quarks and one upper quark 2*(-1 3)+2 3=0, so neutrons.

Neutral.

Electrons are particles of the same level as quarks, and they are currently considered to be the most basic and bottom-level particles, they have no internal structure, and they are all considered to be point-like particles.

If an electron and an upper quark in the proton can approach each other to an ultra-short distance (10 -17 m) below the effect of the weak force, the weak force can pass through the intermediate vector boson, transforming an electron and an upper quark into a hypoquark and an electron antineutrino, the neutrino is released, and the proton becomes a neutron.

As for how the weak force accomplishes "the transformation of an electron with an upquark into a subquark and an electron-type antineutrino by means of an intermediate vector boson", I also don't know.

I asked another physics student at Peking University, and he replied, "Are there any details about this process?" For example, if an electron releases a virtual w- (one of the three intermediate vector bosons) and becomes an electron-type antineutrino, the u-quark receives this w- and becomes a d-quark."

The other four quarks can make up other heavier hadrons, such as k+ meson, k0 meson, d+ meson, d0 meson, b+ meson, b0 meson; 0 hyperon, +hyperon, 0 hyperon, -hyperon, 0 hyperon, -hyperon, -hyperon, c+hyperon, c+hyperon, c0 hyperon, etc.

The number in the figure represents the smallest unit of indivisible positive and negative electromagnetic information - qubits (Qubit) (name physicist John. John Wheeler famously said, "It from bit."

After the development of quantum information research, this concept was sublimated to the point that everything originates from qubits) Note: Bits are bits.

The charge of the proton is +e, so it is composed of 2 upper quarks and 1 lower quark According to the title, three quarks must be located at the three vertices of the equilateral triangle At this time, the electrostatic force between the upper quark and the upper quark should be: fm

k23e×23el

49kel is substituted into the value, and the value is obtained: fm=46n, which is the repulsion force, and the electrostatic force between the upper quark and the lower quark is: fnd

k13e×23el

Substituting 29kEl into the value, we get FND=23N, which is the suction

Answer: The repulsion force between the upper quarks is fm=46n, and the gravitational force between the upper and lower quarks is fnd=23n

The lower quark charge is (-1 3)e i.e. 1 3 negative charges, and the upper quark band +(2 3)e i.e. 2 3 positive charges.

Protons are composed of two upper quarks and one lower quark, 2*(+2 3)-1 3=1, so the protons in the sparrow carry a positive charge of one unit of this mountain.

The neutron is composed of two lower quarks and one upper quark 2*(-1 3)+2 3=0, so the neutron is not charged.
