List-I List-II (A) Total number of orbitals in a shell (I) 2l+1 (B) Total number of orbitals in a subshell (II) n^2 (C) Maximum number of electrons in a subshell (III) 2n^2 (D) Maximum number of electrons in a shell (IV) 4l+2 Choose the correct answer from the options given below:

Options

  1. A(A)-(I), (B)-(II), (C)-(III), (D)-(IV)
  2. B(A)-(II), (B)-(I), (C)-(IV), (D)-(III)
  3. C(A)-(II), (B)-(I), (C)-(III), (D)-(IV)
  4. D(A)-(III), (B)-(IV), (C)-(I), (D)-(II)

Correct answer

B. (A)-(II), (B)-(I), (C)-(IV), (D)-(III)

Step-by-step solution

The total number of orbitals in a principal shell of quantum number n is given by n^2 . The total number of orbitals in a subshell of azimuthal quantum number l is equal to the number of permissible values of the magnetic quantum number, which is 2l+1 . Since each orbital can accommodate a maximum of 2 electrons, the maximum number of electrons in a subshell is 2(2l+1) = 4l+2 . Similarly, the maximum number of electrons in a principal shell is 2n^2 . Therefore, the correct matching is (A)-(II), (B)-(I), (C)-(IV), (
