Question

How are there positive and negative charges when electron itself is negative?

Answer 1

"Static" or imbalanced charges can be created by removing electrons from a neutral atom. They can also be created by adding or removing charged atoms from an object, and the atoms being removed can be negative OR POSITIVE ions.Proton—positive; electron—negative; neutron—no charge. The charge on the proton and electron are exactly the same size but opposite. The same number of protons and electrons exactly cancel one another in a neutral atom.

Answer 2

A body acquires charge when there is a difference in the number of electrons and protons in it.

If the number of electrons is more than the number of protons, it acquired negative charge.

If the number of electrons is less than the number of protons, it acquired positive charge.
