What is the radial distribution function P(r) for a 2pz orbital? What is the probability of finding an electron in a shell of 1.00 pm thickness at radius 50.0 pm?
For a 2pz orbital, the radial distribution function P(r) is given by = P(r) = r2R2p2 .
Here, R2p is the radial wave function for the 2pz orbital.
We also know that, the radial wave function is = R2p = (1/2√6) × ρ × Z3/2 × e-ρ/2.
Here, r = radius expressed in atomic units, Z = effective nuclear charge for that orbital in that atom and ρ = 2Zr/n where n is the principal quantum number (2 for the 2porbitals).
Therefore, P(r)= r2 * (1/2√6) × ρ × Z3/2 × e-ρ/2)2.
