May I ask if it is the size of the electrons or quarks?

There are electrons and nuclei in atoms, protons and neutrons in nuclei, and quarks smaller than neutrons and protons! Got it.

Volume is a macroscopic physical quantity, and for microscopic elementary particles, the concept of "volume" has no practical meaning.

The volume of a molecule atom is obtained by the ratio of the volume of the solid form of the substance to the number of molecules at a certain temperature, and does not take into account the gap between the molecules and atoms.

If you want to compare the scales of electrons and quarks, it is recommended that you compare their masses: the electron mass is about mev (c 2), while the two quark masses that make up neutrons and protons, the upper quark is about 4 mev (c 2) and the lower quark is about 5 mev (c 2).

Quarks are smaller; A quark is an elementary particle that participates in strong interactions and is also the basic unit that makes up matter. Quarks combine with each other to form a composite particle called hadrons. The most stable of hadrons are protons and neutrons, which are the units that make up the nucleus of an atom.

Due to a phenomenon called "quark confinement", quarks cannot be directly observed or separated, but can only be found in hadrons. For this reason, much of what we know about quarks comes indirectly from the observation of hadrons.

Can't compare.

Although quarks have not been observed individually, their mass is estimated. The mass is several times the mass of the proton, because the energy used to blast the hadron of the proton class is accepted by the particle, and the mass will be larger (for example, the mass of the quark is more than 3 times that of the proton, and the mass of the bottom quark is more than 10 times that of the proton), and the mass is usually expressed by energy in physics, for example, the value of the quark is 1350mev.

In general, the radius is not used in quantum physics, so the size of the elementary particles is really not clear, but we only know that the electromagnetic radius of the proton is measured in the experiment, that is, the charge distribution radius is Fermi, and the electromagnetic radius of the neutron is roughly equal to the electromagnetic radius of the proton. The high-energy collision experiment of electrons shows that even if the radius of the electron is not zero, it should be less than 2/1000 Fermi.

This means that elementary particles such as electrons cannot be observed in terms of the amount of space they occupy, and they can still be regarded as "point" particles, so they are not easy to compare with quarks, which are also elementary particles.

Quarks are smaller levels of matter than electrons, and there is no direct evidence for the existence of quarks, only indirect evidence for the existence of quarks.

So electrons are bigger than quarks.

Hope to help you.

Both electrons and quarks are smaller than 10 -16 cm.

The electron rest mass is.

Quark : The mass of a free quark, since three quarks make up a proton, the mass of an average quark is.

The mass of the quark itself is about 1% of that of the free quark

The quark mass is greater than the electron mass.

So far, it has not been found that electrons have an internal structure, and electrons are not composed of quarks. Electrons are elementary particles that have not been able to continue to decompose so far.

Particles are classified into 3 types in terms of species: leptons (without quarks), intermediate trace bosons (without quarks, e.g. photons), and hadrons (poses are composed of quarks, e.g. protons and neutrons).

Electrons belong to the lepton category and do not contain quarks.

Both quarks and electrons are smaller than 10 -16 cm.

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 volume of a single wheel, the electrons are definitely smaller than quarks! The smallest known to be a "neutrino" is one millionth of an electron! If an electron is the size of the sun, then neutrinos are the size of the Earth!

The mass of the electron, approximately. The mass of the quark, approximately. So the mass of the electron is less than the mass of the quark.

Let's go into more detail.

1.Electrons: Electrons belong to leptons, and there are three known types of leptons, electrons, electrons, and tau tons. Leptons are point particles, what does it mean? It is to think that leptons are a point without volume. So, leptons should be the smallest.

2.Quarks: Quarks are blocks that make up hadrons, so quarks are also very small, but quarks are large and small, and quarks are on the Fermi scale, that is, on the order of 10e-15 meters.

To this day, humanity has.

It is found that matter is made up of molecules and atoms, and atoms are made up of negatively charged electrons and positively charged nuclei. Further down, matter can be divided into hadrons, which are composed of quarks, including upper quarks, lower quarks, singular quarks, quarks, bottom quarks, and top quarks; Leptons – including electrons, electron neutrinos, subons, subneutrinos, subons, subneutrinos; There are also propagators – various gluons that transmit strong action.

Now, according to the generally accepted Standard Model, quarks and leptons are placed at the same level of matter, and the basic components of matter that cannot be divided are quarks and leptons. They also exchange photons, three kinds of weak force particles, and eight kinds of gluons to achieve three interaction forces: strong, weak, and electromagnetic. According to the characteristics of the force, particles are divided into three categories: hadrons, leptons, and propagators.

Hadron is a general term for all the particles involved in the action of strong force, protons, neutrons, mesons, etc., all belong to hadrons, and they are made up of quarks. Quarks have six "flavors", which are upper, lower, strange, charming, bottom, and top, and each quark has three "colors", namely red, green, and blue. So what are the types of quarks?

The six "flavors" and three "colors" are eighteen kinds of quarks, plus the eighteen kinds of anti-quarks of their respective antiparticles, and the types of quarks should be thirty-six. Leptons are only involved in weak forces, electromagnetic forces, and gravitational forces, but not in strong interactions. There are six types of leptons, namely electrons, electron neutrinos, electrons, subneutrinos, subneutrinos, subsons, and subneutrinos.

With the addition of their respective antiparticles, there should be twelve types of leptons. Propagators also belong to elementary particles. There are eight kinds of gluons that transmit strong interactions, and there are three kinds of intermediate bosons that transmit weak interactions: w+, w-, and z0, as well as photons that transmit electromagnetic effects, so there should be twelve types of propagators.

In the Standard Model, which does not involve gravity, quarks, leptons, and propagators are all placed at the same level of elementary particles, then there are at least 60 kinds of elementary particles that make up the world's matter.
