The more electrons an object loses or gains, the greater the charge it carries? That s right

Not necessarily, you have to see whether he is positively charged or negatively charged, it is possible to neutralize it. For example, aluminum, which is originally positive trivalent, will not be charged if it has three electrons.

Charge. Open Category: Sports.

1] This is ancient electricity.

Target**. Ancient humans have long pointed out the phenomenon of "triboelectric electricity" and recognized that there are two kinds of positive or negative power, the same kind of rejection, and different kinds of attraction. At that time, because they did not know that the power source was connected to the nature of the object's electricity, it was called "charged" and showed this so-called gravitational repulsion or charged body of the object.

Sometimes referred to as a charged body to "charge", as in "free." "Humanity on electricity.

Later development, but the name of the charge has come down.

Charge is the amount of electricity and other matter carried by atoms or electrons. The unit is the coulomb (symbol c) for the abbreviated library.

We often refer to charging as "charged particles", but the charging itself is not a "particle", but we often treat it as a particle for easy description. Therefore, we refer to it as having more charge than those forces and determine the amount of electric field (Coulomb force) in size. Also, according to the directionality of the electric field force, the charge can be divided into positive charge and negative charge, and the electrons of this negative charge.

According to Coulomb's law, objects that will repel each other with the same kind of charge and will attract each other to different objects responsible. The product of the charge repulsion or force of attraction is directly proportional.

Point charge. The ideal mode for charged particles with point charges. The true point charge does not exist, only when the shape and size of the charged particle, the size of the particle, or the charged particle is sufficient to affect the interaction force at a distance much greater than ignoring this charged body can be referred to as a "point charge."

The intrinsic properties of matter. There are two types of charges: positive and negative.

When, due to friction, heat, radiation, chemical changes, etc., the purpose of losing some positively charged electrons for the purpose of local objects is negatively charged. An object with an excess of positive or negative charge is called a charged body, and a charged body is sometimes referred to as an electric charge. Yes.

Interactions between charges. The electrostatic charge that is generated in the space around the electrostatic field, in addition to moving the charge in different places, also produces a magnetic field to generate electricity. Therefore, the electric field force experienced by a stationary or moving charge can only be a charge that will move by magnetic force.

A charged body can be seen as a practical point charge that is charged not only with the body itself, but also depending on the nature of the problem and accuracy requirements. Abstract point charge is established when necessary to establish the basic law and is the essence of the problem analysis when complex analytical tools. For example, the quantitative study of the interaction between Coulomb's law established the concept of an electric charge applied to a point by establishing the electric field and the charged body charged by the charged body, which was introduced in the test.

Charge. Chinese particle physics, many particles are electrified. In particle physics, charge is additive quantum number, and the law of conservation of charge also applies to the charge of the particle and the reaction of the post-charge particle in the reaction of the particle, which was previously equal to its strong interaction, weak interaction, and electromagnetic interaction role is strictly established.

You don't have a good understanding of why objects are electrified.

Under normal circumstances, both objects are uncharged, i.e., neutral, and the number of positive and negative charges inside and outside the nucleus is equal.

When friction occurs, an object loses several (e.g. 5) electrons, and another object necessarily gains 5 electrons. Electrons are lost because there are 5 electrons missing outside the nucleus and 5 units of positive charge. The electrons are given a negative charge of 5 units because there are 5 extra electrons outside the nucleus.

The silk rubs against the glass rod, the silk gets electrons, the glass rod loses electrons, that is, the electrons on the glass rod are transferred to the silk tassel in the morning, the glass rod is positively charged due to the lack of electrons in the guess bird, and the silk is negatively charged due to the excess electrons.

Note that the excess or lack of electrons is relative to the number of positive charges in the nucleus! The nucleus is very stable, the number of positive charges is constant, and the number of positive charges in the nucleus will not move unless a nuclear reaction occurs.

Because the charge of an object is an integer multiple of the meta-charge. Regardless of the positive and negative charges, the positive and negative charges are all 5, and the charged charge is 5xe = coulombs.

It is the glass rod that loses electrons, so it is positively charged, and these electrons run to the silk, so the silk is negatively charged. The electrons themselves are negatively charged, and each electron carries a negative 19th power of the coulomb. An object is positively charged if it lacks electrons and negatively charged if it has many electrons.

Originally, there was no shortage of electrons on either side, and the result of friction was that the electrons ran from the glass rod to the silk, so the two limbs had equal charges.

This passage should be understood as:

The positive charge of the glass rod is equal to the number of negative charges on the silk.

Since the number of electrons lost on the glass rod is equal to the number of electrons that silk gained from Nonosun, the amount of electric charge (absolute value) shown by the two is equal to the number of electrons.

When electrically neutral, the positive and negative charges are equal, and the number of electrons lost means that there is an equal amount of positive charge!

The electrons of one object run onto another object. One is positively charged and the other negatively charged. The amount of their charge is equal.

The object is positively charged, so Chun Shen is losing electrons.

The number of lost electrons is learned: filial piety.

n=1*10^-8/e=

Where, the amount of electrons is .

Amount of charge:

The amount of negative charge carried by an electron is coulombs (meta-charge), that is, 1 coulomb is equivalent to the total charge carried by an electron. The minimum charge is called the meta-charge.

SI Units: The basic unit of electricity in the SI system of units is the coulomb, and the dimension is i t, 1 coulomb = 1 ampere·second.

Coulomb is a unit of electricity, the symbol is c, referred to as library. It was named in honor of the French physicist Coulomb.

Charge Quantity Test Method:

Under laboratory conditions, the electrostatic properties of the fabric after being charged in the form of friction are evaluated, i.e. the charge surface density of the fabric is tested. The sample is pretreated under the conditions specified in the standard, put into the roller friction machine developed by the Shandong Provincial Institute of Textile Sciences for rolling friction, and generate static electricity, implement the GB 12014-2009 anti-static overalls standard, and deliver the friction sample to the LFY-403 friction charged charge test, and read out the charge of the sample through the electrostatic potentiometer.

1).q=it (where i is the current, unit a, t is time, unit s).

2).q=ne (where n is an integer, e is the meta-charge, and e=coulombs).

3).Q=Cu (where c refers to capacitance and u refers to voltage).

Among all kinds of charged particles, the amount of electron charge is the smallest, and people call the minimum charge the meta-charge, and the amount of charge carried by the electron is e=

So the answer is: c

That is, the greater the value of the ion's bond, the greater the charge of the ion.

(generally proportional to the product of their charges).

NaCl, which is made up of sodium ions and chloride ions, both of which are ions with a unit charge.

MGO, which is composed of magnesium ions and oxygen ions, is known to be ions with a two-unit charge.

The ionic bond of MGO is stronger than that of NaCl, making the oxide of the skin auspicious magnesium.

The melting boiling point is higher than sodium chloride.

The hardness is greater than that of sodium chloride.

The load of an electron is coulombs (c); The amount of charge carried by a proton is + coulomb (c).

Coulombs (c) is the unit of charge in the SI brigade system, which is defined as the amount of electricity that passes through one second at a current intensity of one amperere. The amount of electron and proton charge is an integer multiple of the element charge e, where e c is the basic unit of electron electric hysteresis. Electrons are negatively charged, and their amount of charge is -e, whereas protons are positively charged, and their amount of charge is +e.

Among the various charged particles, the size of the electron charge is the smallest, and people call the minimum charge the meta-electric laughter, and the amount of charge is e=

So the answer is the spine car:

Meta-charge.

Among the various charged particles, the magnitude of the delay bridge type electronic charge is the smallest, and people call the minimum elimination charge as the meta-charge, and the amount of charge carried by the electron is e=

So the answer is guess: c

a. From the schematic diagram of the structure, it can be seen that the number of protons = the number of electrons outside the nucleus = 11, and the number of outermost electrons is 1, which is the atom of the metal trapped element, and it is easy to lose 1 electron to form a cation

b. From the schematic diagram of the structure, it can be seen that the number of protons = 8, the number of electrons outside the nucleus = 10, the number of protons and the number of electrons outside the nucleus are anions, and the outermost shell is 8 electrons, which is relatively stable

c. From the schematic diagram of the structure, it can be seen that the number of protons = the number of electrons outside the nucleus = 10, which is the atom of the noble gas element and has stable properties
