Question

P is the probability of finding a 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 on r is

• A.
• B.
• C.
• D.

Answer 1

Answer: (D)

The probability distribution curve for a 1s electron of the hydrogen atom is given above.

The radial probability function curve for is 1s

Here P is $4\pi r^2{R}^2$

Conclusion: Hence, the correct option (B)
