`P` is the probability of finding the Is electron of hydrogen atom in a spherical shell of infitesimal thickness, dr, at a distance `r` from the nucleus. The volume of this shell is `4pi r^(2)dr`. The qualitative sketch of the dependence of `P` on r is

C

D

Text Solution

Verified by Experts

The correct Answer is:
C
Probabilty of finding 1s electron is maximum near the nucleus and goes on increasing till it reaches a maximum value at a distance 52.9 pm and then begins to decrease abruptly. Even at large distance from the nucleus, there is a finite through small probability of finding an electron of a given energy.
