7Which statement about H-atom is not true? (A) Spherical polar coordinates are the natural choice for H-atom Schrödinger equation because the potential term is spherically symmetric. (B) H-atom Schrödinger equation can be solved by separation of variables where the radial part Rni(r) and the angular partare linked through I(I+1) while Θ(θ) andΦ (Φ) are linked through m². (C) The operator for the z-component of angular momentum has the simplest form in spherical polar coordinates as opposed to the x and y-components. (D) The rules for allowed angular momentum magnitudes and orientations are shared by the rigid rotor and the H-atom. (E) By changing the variable sinθ into x, the Θ differential equation can be recognized as being the associated Legendre equation.
