We find the radius at which the radial distribution function of
the hydrogenic
orbital has a maximum value by solving dP/dr = 0.
P(r) = r2R(r)2
P2s = r2 ( 2- Zr/a0)2 *1/8 *(Z/a0)^3 *e−Zr/a0
dP/dr = 0 = r*( 2- Zr/a0)*1/8 *(Z/a0)^3 *(r^2/ao^2 - 6r/a0 + 4)*e−Zr/a0

r (m.p) =[(3 + 5^1/2)a0 /Z]
z=2 ;, a0 = 52.9 pm
r (m.p) ( for He+ in 2s )= 138 pm

Determine the most probable distance from the nucleus for an electron in the 3d orbital of a hydrogen atom. The radial wave function, R.(r), for the 3d orbital is given by R32 %) = 3,45 (7)*()*** Give your answer in terms of ao.
Consider an electron in a 2s orbital of hydrogen (Z=1). Calculate the probability that the electron will be found anywhere in a shell formed by a region between a sphere of radius r and radius 1.0pm greater than the r value. Do this calculation in Excel for r from 1 to 600 pm in increments of 1pm. (You will be calculating the probability for successive shells at greater and greater distances from the nucleus.) Plot the resulting curve with probability...
