Question

In nature, both positive and negative electric charge exists. However, both in the textbook and in our discussions from lecture, electrical charge is considered as most commonly being solely transferred by movement of electrons. Explain why this assumption (i.e., that the manifestation of electric charge is usually due to re-organization of electrons) is reasonable. (Hint: you might consider the question from an atomic scale viewpoint)​

Answer 1

atom havr both proton which are positively charged and electrons which are negatively charged.

proton reside inside nucleus and electron in the shell which is outer part of atom. so electron can be removed from atom but proton cannot.

so when we remove a electron from a atom that atom has one deficiency of electron so atom does not remain neutral and gains positive charge. so this movement of electron is responsible for both negative and positive charge motion
