`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

Options

A.
B.
C.
D.

Answer

C

Explanation

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.
