Given below are two statements:\n Statement I: Boundary surface diagrams of constant probability density enclose a region where the probability of finding the electron is 100%.\n Statement II: The probability density \( |\psi|^2 \) has a finite value even at very large distances from the nucleus, making a 100% boundary surface impossible. \nIn the light of the above statements, choose the most appropriate answer from the options given below:

  1. A
    Both Statement I and Statement II are correct.
  2. B
    Both Statement I and Statement II are incorrect.
  3. C
    Statement I is correct but Statement II is incorrect.
  4. D
    Statement I is incorrect but Statement II is correct.
View Answer & Solution

Correct answer · Option D

Statement I is incorrect but Statement II is correct.

Explanation

Statement I is incorrect because boundary surfaces typically enclose 90% probability, not 100%. Statement II is correct because \( |\psi|^2 \) extends infinitely.
