50 Most Frequently Asked Questions About Electrons | Chemistry

In this article, I will take you through 50 Most Frequently Asked Questions About Electrons that every learner must be aware of especially the ones who is preparing for Competitive exams. Electrons belong to the first generation of the lepton particle family, and are generally thought to be elementary particles because they have no known components or substructure. The electron has a mass that is approximately 1/1836 that of the proton. We will see some of the most frequently asked questions about electron in below section. More on wikipedia.
