Caculate the expectation value (r) for an electron in the ground state of the hydrogen atom. remember, the maximum of the radial ground state wavefunction, i'mar, is equal of the bohr radius. is the expectation value (r) larger, equal or smaller than i mar? give a brief explanation. b) (10 pts] using the expectation value (r )nim = 1/(aon) and the energy values for an electron in a bound state (nlm) of the hydrogen atom, show that the expectation values of the kinetic energy operator t and of the potential energy v are such that: 2(t)nim = -(v)nlm
