Question

P is the probability of finding the 1s electron of hydrogen atom in a spherical shell of infinitesimal thickness, dr, at a distance r from the nucleus. The volume of this shell is $4\pi r^2$dr. The qualitative sketch of the dependence of P or r is:

• A.
• B.
• C.
• D.

Answer 1

The correct option is B

R = 0, 4${\pi }^2$dr = 0
No. of radial modes = n - l - 1
= 1 - 0 - 1 = 0
