The Schrodinger wave equation for hydrogen atom is `Psi("radial")=(1)/(16sqrt(4))((Z)/(a_(0)))^(3//2)[(sigma-1)(sigma^(2)-8sigma+12)]e^(-sigma//2)` where `a_(0)` and Z are the constant in which anwer can be expressed and `sigma=(2Zr)/(a_(0))` minimum and maximum position of radial nodes from nucleus are .... respectively.
