Do electrons move randomly, with no preference of directions? And why electrons don't fall into the nucleus? About this question, I read the article on Chemistry wiki, which says that when electron falls towards nucleus, its kinetic energy becomes extremely large so there is a battle between electrons and nucleus, and no one is gonna win the battle, there is a compromise state instead. My question is why can't we say that electrons with great kinetic energy are moving towards the nucleus? Why should it escape?
