Charge definition: The amount of charge charged by an object or the particles that make up an object, which is the algebraic sum of the meta-charges in the object or system.
The meta-charge is the absolute value of the charge carried by an electron, or the charge carried by a proton. As for why the size of the charge is an integer multiple of the meta-charge, it is because humans have not been able to separate quarks, so there is no electricity smaller than the meta-charge. As to whether or not it is an actual substance that you mention, there is no dispute that it is a substance that actually exists.
Negative charges are completely different from electrons, or in positive matter, negative charges are made up of a large number of electrons. The difference between free electrons in metals and free charges in conductors is that the former is negatively charged, while the latter can be both positive and negative. (All of the above expressions refer to positive substances).

Produced in the process of friction, the object has the ability to attract small and light objects, and we say that the object is electrified. That is, it has an electric charge.
The amount of matter contained in an object this year is called mass, and the amount of charge carried by an object is called electricity, both of which are properties of the object, that is to say, it is they that constitute the actual object.
The amount of matter contained in the electron is the mass, the mass of the electron is me, the charge carried by the electron is a meta-charge, the property is negative, and it is denoted as -e. When we say electron, we mean that the particle has a mass of me and has a charge of -e, and when we say negative charge, we say that the object has a charge of -e or several -e.
Free electrons in metals refer to electrons that can move freely, because the positive charge is a proton belt, it is fixed in the nucleus, it cannot move freely, only electrons can move, and it can move freely in all directions, so we usually call it free electrons.
Free charge in conductors: conductors can be metals, conductive liquids, 、、、, etc., in which they can move freely may be electrons, positively charged ions, or negatively charged ions, these charged particles, we collectively call free charge.

Positively and negatively charged elementary particles are called electric charges, and positively charged particles are called positive charges (the symbol is "+" and negatively charged particles are called negative charges (the symbol is " " is a practical problem. Electrons are a type of charged particles (speaking of which, you can think of electrons as a type of electric charge) Negative electrons exist around the nucleus, positrons are rare, and are generally only involved in nuclear reactions, and electrons are usually negative electrons. The free electrons inside the metal are part of the free charge.

Charge refers to the amount of electricity carried by electrons, negative charge refers to the total amount of electricity carried by electrons, and electrons are those things outside the nucleus.

Charge is the amount of electricity carried by a substance, atom, or electron, etc. The unit is the coulomb (denoted C) for short, the library.
The electric field acts on the directionality of the Senkai bridge force, and the charge can be divided into positive and negative charges, and the electrons are negatively charged.
Characteristics of electric charge.
There are only two kinds of electric charges in nature, namely positive and negative.

1.The meta-charge is the charged charge of a single electron or proton, with a magnitude of e, which is the smallest unit of electric charge;
Stipulate: electrons have a negative charge of 1 unit, and protons have a positive charge of 1 unit;
2.The positive charge is the amount of electricity carried by the electrons, while the negative charge is the amount of electricity carried by the protons.
Because 1 electron and 1 proton carry the same amount of electricity, but the electrical properties are opposite, one positive and one negative are specified. In other words, if scientists had defined the charge carried by electrons as positive and the charge carried by protons as negative, it would have been fine. It's just that since it was previously stipulated that protons are positively charged and electrons are negatively charged, it has been used all the time and has not changed.

You have a lot of questions. One by one, they answered
Can electrons be understood as negatively charged?
Electrons have a negative charge, which is a property of electrons.
The amount of electricity is one unit, and there is no smaller charge in nature except for smaller quarks that have fractional charges.
Does positive and negative charge refer to the properties of particles or the positive and negative charges exhibited by objects?
Is it true that all objects are electrically charged, but most of them are not electrically charged, so what exactly does the amount of charge mean, these two answer together:
Matter is made up of atoms, which contain electrons (negatively charged), protons (positively charged), and neutrons (uncharged). Electric charge is a property of these microscopic particles. Normally, when the number of electrons in a matter is the same as the number of protons, the object is neutral.
When the number of electrons in an object is greater than the number of protons, it becomes negatively charged, and when the number of electrons is less than the number of protons, the object becomes positively charged. The amount of charge is the sum of the excess electrons or protons that have been charged.
The attraction of charged particles or what? Does it have anything to do with the positive and negative properties of the particles?
It refers to the interaction between two objects with a different charge, and the two objects will only attract when they are charged positively or negatively, and will repel when they are the same.

The charge is the positive or negative charge carried by the object or the particle that constitutes the object, and the positively charged particle is called the positive charge (the symbol is "+" The negatively charged particle is called the negative charge (the symbol is " " is also a property of some elementary particles (such as electrons and protons), the same charge repels each other, and the different charges attract each other.
In electromagnetism, electric charge is a physical property of matter. A substance with an electric charge is called an "electrically charged substance". Two charged substances exert forces on each other and feel the forces exerted by each other, and the forces involved obey Coulomb's law.

The charge is naturally existing and is the smallest charged particle, and the charge can be abstracted into a charged point proton is positively charged, because the proton is the carrier of the positive charge, and the carrier electron described as the proton is positively charged is negatively charged, because the electron is the carrier of the negative charge, and the carrier described as the electron is the carrier of the negative charge Although the proton electron is the carrier of the charge, it cannot be understood that the charge constitutes the proton or electron, and the composition and bearing are different concepts.
-
Charge is a property. The amount of charge is a description of the strength of this property. However, we found that all charges are integer multiples of the charge of protons and electrons, so we think that the amount of metacharge is the charge charge of the electrons.
It wasn't until later that we discovered quarks, but that's a subject of quantum physics.

Electrons are not charges. Charge is the amount of electricity carried by electrons, which are negatively charged.
The charge "one is" the "basis guess" and the "electron" one is"Carriers"。It's like if you have money, the amount of money is the electric charge, and you are the electron. Therefore, the stricter Chi Feng said that the charge cannot move, but the electron can.
Conclusion: The current is formed by the directional movement of the charge, and the positive charge is prescribed.
The direction of rapid movement of the directional code is the direction of the current.

An electron is a negative charge, whereas a negative charge is not necessarily an electron. The first elementary particles to be discovered. Negatively charged, often denoted by the symbol e.
It was discovered in 1897 by the British physicist Joseph John Thomson while studying cathode rays. All atoms are made up of a positively charged nucleus and a number of electrons moving around it.
E-Profile
Electrons are negatively charged subatomic particles. It can be free and sensitive (does not belong to any atom) or it can be bound by the nucleus. The electrons in the tung atom exist in spherical shells with a wide variety of radii and energy levels.
The larger the spherical shell, the higher the energy contained in the electrons.
The directional motion of the charge forms an electric current, like the current in a metal wire. Using electric and magnetic fields, the movement of electrons can be controlled as needed (in solids and vacuums), and various electronic instruments and components, such as various electron tubes and electron microscopes, can be manufactured.
The atom, the basic unit of matter, is made up of electrons, neutrons, and protons. Neutrons are not charged, bridges make protons positively charged, and atoms are not electrically charged. Relative to the nucleus of neutrons and protons, the mass of electrons is extremely small.
The mass of a proton is about 1840 times that of an electron.

Sartre said in "Existentialism is a Humanism":
Atheistic existentialism -- I'm one of its representatives -- I'm more self-justifying; It asserts that if God does not exist, then at least one thing always exists before its essence; There must be the existence of this thing first, and then what concept can be used to explain it. This thing is man, or according to Heidegger, human reality. >>>More

Love, mainly depends on how you treat it, I think: plain love is true, when you fall in love with someone, don't care about the romance of love and many ways of love, everyone has a different way of love, don't be dissatisfied, too greedy, you will lose rare true love, Some people say that love will not last long, I think it is wrong, love has a long time, because it is not done to protect true love, It will lead to love is short-lived, thinking that love will not last long Love someone: trust each other, love someone to understand each other. >>>More
