The wavefunction for the hydrogen atom in the 2s state is psi(r)_2s = 1/squareroot 32 pi a^3_B (2 - r/a_B)e^-r/2a_B verify that this function is normalized. in the Bore, model the distance between the electron and the nucleus in the n=2 state is exactly 4a_B. Calculate the probability that an electron in the 2s state will be found at a distance less that 4a_B from the nucleus.
