What keeps electrons in an atom from flying away or falling into the nucleus?

Question

In atoms, what force or charge, etc. keeps electrons from flying away or into their nucleus? is there a kind of weak-force at work on the atomic scale? Note I am aware the electron positions are only abstract variables and can be referred to as the electron field and the like. This is not the question. What is the reason an electron is bound to that nucleus to the point it can sustain an "orbit" or variable probability path, and not fly away or into it's nucleus?

Answer 1

To keep things simple, electrons are attracted to the protons in the nucleus of an atom. It is this attraction that holds the electrons in place. This is the reason that atoms, usually, have the same number of protons as to electrons. I say usually because when you get into freshman chemistry, this rule is not so cut and dry.
