What is the boundary of an atom?
« on: 11/08/2016 21:53:01 »
Jonathan Thomas asked the Naked Scientists:
   I recently read about the 'wave function' in quantum physics which explained that the precise location of,  say,  an electron at a particular time cannot be determined,  but rather the wave function describes the likelihood of the electron being found at different locations in space (This was in Jim Al-khalili's book Life on the Edge on page 48)

My question is -  could the electron be literally anywhere in the universe or does it have to be in the confines of the atom,  and if so,  what is the 'boundary' of an atom?
What do you think?

The boundary is the end of the universe.
