how an electron got negative charge?

Answer 1

hey as me know they all are made of the elementary particles so than the elementary particles are called quarks,theer are three type of quarks.they are the up quark,down quark & the middle quark.the value of these are that it is -1/3,1/3,1/3 so when it it made of three up quarks whose values are -1/3+-1/3+-1/3 that gives u the answer that is -1 there fore the charge of electron is -1ok

Answer 2

The current convention of assigning negative charge to electrons was made by Benjamin Franklin. He unfortunately assumed that charge moved in the opposite direction that it actually does, so objects he called "negative" (representing a deficiency of charge) actually have a surplus of electrons. By the time the true direction of electron flow was discovered, the nomenclature of "positive" and "negative" had already been so well established in the scientific community that no effort was made to change it.

Answer 3

By the time electrons were discovered, electricity was reasonably well understood. Scientists were able to determine that an electron was attracted to areas of relatively positive voltage and repelled from areas with relatively negative voltage. As theory was developed, it was determined that like charges repel, and unlike charges attract.

Thus, scientists assigned electrons a fixed, negative charge in coherence to this convention.

Answer 4

By rubbing a balloon on its head?

Seriously, an electron is merely a wave-particle that we know always carries the same electrostatic charge. The charge happens to be opposite that of protons. Human beings assigned them names like positive and negative. An electron always has that charge whether you call it negative or not.

Did I misunderstand your question?

Answer 5

As I understand it an electron "IS" the negative charge.

Answer 6

it is a convention given, nothing else.
a way to diffrentiate things for better understanding
