Why the electrons have only negative charge why not positive charge?

There is a real force associated with the electron. This little guy has a "force field" standing around it at all times. All day, every day. It cannot be made to go away. This field of force has been given the name "electric" and it is an electric (force) field. We also give the designator "negative" to that field to identify its polarity. That's because the force field has "direction" associated with it. In sum, the electron has this field around it because it cannot "not" have it. The negative electric field of the electron is an intrinsic quality that cannot be separated from it. When an electron comes into existence, it appears with its negative charge, and that's what make it negative.

∙ 13y agoThere really isn't a reason why the electron is negative. It is just known that the electron is negative. It could be that since the proton is positive, the electron is negative to balance out the charge of the atom.

You can't do that because one doesn't exist without the other. They are part and parcel of the same thing: the electron. An electron is a fundamental particle that is the carrier of the negative electrical charge. The electron has that charge because the charge is part of what it is; the electron was "born" with the negative electrical charge. That's why it has it.

The reason why electrons have a negative charge is because without that charge, the positively charged protons would repel the electrons and one another.

Electrons themselves are negatively charged because they produce and are affected by electromagnetic fields due to a mysterious fundamental conserved property regulating electromagnetic interaction. It is the intrinsic nature of an electron to carry charge.

∙ 12y agoElectron being negatively charged is held up by the positively charged nucleus. If electron is to be removed away from the clutch of the nucleus then work by spending energy is to be done. The formula for the energy of the system of charges is given as 9*109*Ze*(-e)/r2
Hence the energy becomes negative. As we add positive energy along with this negative energy, then the negativity is reduced. So the maximum possible energy for the electron would become Zero. Here the electron is almost out of the clutch of the nucleus.
In case of hydrogen atom, the minimum energy of the electron is -13.6eV being in the first ie closest oribit. So to remove the electron out of the clutch we have to supply +13.6 eV energy. This is known as ionisation energy. And 13.6V is the ionisation potential.
If suppose an electron is kept in between two plates with potentiall difference V then 1eV will be the potential energy gained by the electron. Immediately that potential would be changed into kinetic form as 1/2 m v2 where v is the maximum velocity attained by the electron. m-mass of the electron.

∙ 12y agosame reason the proton has a positive charge.
Wiki User

Does the nucleus of an atom have a positive electric charge?
Yes it has a positive charge. A nucleus is made up of protons that have a positive charge and neutrons which have no charge so are are neutral. So, overall, the nucleus is the positively charged part of an atom and its positive charge is neutralized by the negatively charged electrons which revolve around the nucleus.
If an atom has 5 protons and 7 electrons what is the charge of the atom?
its charge is 0. Protons have a positive charge, while electrons have a negative charge (neutrons have no charge at all). So ten protons will balance out ten electrons, making the net charge 0.
Is the Nucleus of an atom can have both positive and negative charge?
the nucleus has only positively and negatively charged particles. the negative particles (electrons) orbit around the nucleus
Why does negative charge move and not positive?
An isolated positive and negative can move for example in an electric or magnetic field. But in metals only the electrons can move since the positive charge is bound to the metal lattice by attractive forces.
What happens When a positively charged conductor is earthed?
As we know that in normal current flow, electrons passage is always from the negative to positive side , now in the case of earth it acts as a ground to the positive charge, and current flows from positive charge to the earth, which acts as a anode and as we know a passage of current occurs only if there is negatively charge electron flowing towards positively charged cathodes. So electrons may flow from earth neutralizing the positive charge.
What results after an atom gains electrons?
Electrons have a positive charge and protons have a negative charge. An atom's nucleus is 99.95% of its weight. When an object gains more electrons, it gains a negative charge that over comes the positive charge. This only happens when there are more electrons than protons.
How does body becomes negatively charge?
It gains electrons. The only charged particles which can freely move from one object to another are electrons. Electrons have negative charge. So adding electrons gives a negative charge, and removing electrons gives the object a positive charge.
Why do elements acquire positive charge on gaining electrons?
They do not. An electron is negatively charged and an atom can only acquire a negative charge on gaining electrons.
The charge of electrons?
Electrons have a negative charge. The easy way to remember it is because the names of the other two particle types which make up an atom sound like what they are: Proton is Positive Neutron is Neutral So you're only left with the negative charge, which must be assigned to the electron.
What particles around the atom have negative charge?
only the electrons have a negative charge but they go around the nucleus
If an atom of an element has six protons and eight neutrons how many electrons is in this atom if its neutral?
When we consider charged particles, we are only concerned with protons and electrons. Neutrons have no charge, so they don't contribute to a positive or negative charge. Protons have a positive charge and electrons have a negative charge. They are both equally positive and negative, that is to say one proton cancels out the charge of one electron. So as long as there are equal numbers of protons and electrons, the particle will be neutral. If there are six protons, then there needs to be six electrons in order to be neutral.
Does the nucleus of an atom have a positive electric charge?
Yes it has a positive charge. A nucleus is made up of protons that have a positive charge and neutrons which have no charge so are are neutral. So, overall, the nucleus is the positively charged part of an atom and its positive charge is neutralized by the negatively charged electrons which revolve around the nucleus.
What has a negative charge and is inside the nucleus of an atom?
Nothing. The only part of an atom with negative charge are the electrons.
Is the charge of a proton posistive or negative?
A proton is positive.Proton = PositiveNeutron = NeutralThere is only one subatomic particle left and one charge left, electron and negative
If an atom has 5 protons and 7 electrons what is the charge of the atom?
its charge is 0. Protons have a positive charge, while electrons have a negative charge (neutrons have no charge at all). So ten protons will balance out ten electrons, making the net charge 0.
Why is the nucleus's charge positive?
because the nucleus consists of protons and neurons- protons are positively charged and neutrons have no charge, therefore in total it is positive. however the nucleus is surronded by electrons which have a negative charge... the same number of protons and electrons cancel eachothers charge but the nucleus has a positive charge because it only has protons, no elecrons
An atom may have a positive charge a negative charge or be electrically neutral How does an atom develop a negative charge?
It becomes negative only if gains more electrons. Once it gains electrons its now called an ion. ions form because they want to fill their valence electron shell.
