electricity is the flow of electrons and in byjus video they said electrons revolve around protons and neutons(nucleus) how can electrons move in a direction when protons are attracting them and if protons move along with electron they dont generate electricity as stated in Byjus video.

Solution

You are right that electrons revolve around nucleus i.e. protons,and protons attracts the electrons with a great force .

The electrons on the outer orbit of the atom are called valence electrons. With enough outside force, a valence electron can escape orbit of the atom and become free. Free electrons allow us to move charge and thus generates electricity.

Q. Ever wonder when you look at things in the surrounding, what are they made up of? No? Everything in your surrounding including you, are made up of atoms. Now what is an atom? Atom is made up of electrons, protons and neutrons. Electrons revolve around the protons and neutrons. Protons are positively charged and electrons are negatively charged while neutrons have no charge. Protons are not free to move, hence only electrons can move if we provide them enough energy. The particle which is responsible for the heating of appliances is ______.

I learnt this in atoms and molecules chapter "Two protons will also tend to repel each other because they both have a positive charge. On the other hand, electrons and protons will be attracted to each other because of their unlike charges."but I have a doubt, that is, if protons can attract electrons,then why electrons in the atom is revolving around the protons and not attracting it.
