No single answer !! This should be a textbook question in Quantum
Mechanics !!

Hi
The expectation value of the momentum of bound states in atoms should
be zero. That means that the integral of Ebsi(r)*d Ebsi(r)/dx over the
whole space should be zero and so for y and z. Mathematically how
this is always satisfied ? I.e, What ensures the validity of this
condition?
Thanks
