Problem 10 (Problem 2.24 in textbook) The wavefunction for the electron in a hydrogen atom in its ground state (the 1s state for which n 0, l-0, and m-0) is spherically symmetric as shown in Fig. 2.14. For this state the wavefunction is real and is given by exp-r/ao h2Eo 5.29 x 10-11 m. This quantity is the radius of the first Bohr orbit for hydrogen (see next chapter). Because of the spherical symmetry of ịpo, dV in Eq. (2.56)...

1) (60 points) The ground state of the hydrogen atom: In three dimensions, the radial part of the Schrodinger equation appropriate for the ground state of the hydrogen atom is given by: ke2 -ħ2 d2 (rR) = E(rR) 2me dr2 where R(r) is a function of r. Here, since we have no angular momentum in the ground state the angular-momentum quantum number /=0.

(a) Find (r) and (r2) for an electron in the ground state of hydrogen. Express your answers in terms of the Bohr radius a. If a measurement on r is performed for the ground state wavefunction, what is the most probable value? (b) Find (x) and (x2) for an electron in the ground state of hydrogen. Hint: This requires no new integration-note that r2 = x2 + y2 + z2, and exploit the symmetry of the ground state.
