# What force keeps electrons in their orbitals and not collapse into the positively charged nucleus? [duplicate]

I know about quantum mechanical model of an atom and how electrons behave like a standing waves and there isn't any lower level energy available for electrons below ground state energy and energy comes in discrete packets and so on...

I am just having a hard time to imagine and understand that why electrons, which are negatively charged and nucleus of an atom which is positively charged, because of protons remains separated from each other .

I mean opposite charges attract each other; so why electrons just stay in there orbitals and not collapse in the nucleus which is positively charged ?

What is that force which keeps electrons in their orbitals and thus overcome the attractive force which is being applied by the protons ?

• The electromagnetic force - they are collapsed into the positively charged nucleus. Quantum mechanics just specifies they collapse in a special way. – GPhys Jan 24 '16 at 3:09
• It's worth note that an attractive force is not sufficient to imply collapse must happen anyway - the obvious counterexample is planetary orbits. It turns out this isn't sufficient to describe electrons, though. – GPhys Jan 24 '16 at 3:13
