The ground-state wavefuntion of a hydrogen atom is Y=(1/((pi)a^3))^(1/2)*e^(-r/a) where a=bohr radius. a) calculate probability that the electron will be found within a small sphere of radius 1pm on the nucleus. b) no what if the sphere is at r=a. What is the probability that the electron is inside it? (assume the volume element is so small that Y soes not vary within it (ie it can be treated like a constant))
