To the question "What is between the parts of an atom"
(The electrons and the nucleus) you once answered "nothing". Given the
vast relative spaces involved, and the sheer numbers of atoms, this
makes for a lot of nothing. Can you elaborate on that answer a
little? What is between the electrons and nucleus of an atom?
A lot of nothing.
Richard Barrans Jr., Ph.D.
How can one elaborate on 'Nothing'?
Remember that the electrons have a probability of being found at just about
any location in the atom -- the atomic orbitals are pictures of the the
probability density function for the electrons. The atomic orbitals have
nodes where the electrons will never be found. Otherwise the electrons can
be found pretty much anywhere. However, if the electron is not there (and
neither is the nucleus) then 'NOTHING' is there, i.e., vacuum. And yes, that
is a LOT of 'NOTHING'.
