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

Answer 1

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.

Answer 2

Electrons have a negative charge because they are fundamental particles with that specific property. There are other particles, like protons, that have a positive charge. This charge difference allows for the attraction between electrons and protons, which is essential for the formation of atoms.

Answer 3

There 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.

Answer 4

Because they do. Sounds stupid, but that's the bottom line. You can't "remove" the electrical charge and look at it or look at mass that remains after removing the charge. 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.

Answer 5

Electrons move in circular orbits around the nucleus, this is because there is an electrical attraction between the negative charge of the electron and the positive charge of the protons in the nucleus. The reason why electrons have a negative charge is because without that charge, the positively charged protons would repel the electrons and one another.

Answer 6

Generally, a negative charge is regarded as more electrons than protons. 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.

Answer 7

Electron 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.

Answer 8

same reason the proton has a positive charge.

Answer 9

By convention, the negatively charged sub atomic species are named as electrons and positively chargedsub atomicspecies are named as protons.
