why do electrons n protons have equal charge?
The number of charge on electron and proton is equal in order to make the atom electrically neutral.
Why are protons positively charged, electrons negatively charged and neutrons have neither negative or positive charge?
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.
