Given below are two statements: Statement I : Azimuthal quantum number ' ( ) ' identifies the subshell and determines the shape of orbital. Statement II : There are ((2 +1) ) orbitals of each type in a subshell. In the light of the above statements, choose the most appropriate answer from the options given below:

Options

  1. ABoth statement I and statement II are correct.
  2. BStatement I is correct but statement II is incorrect
  3. CStatement I is incorrect but statement II is correct.
  4. DBoth statements I and statements II are incorrect.

Correct answer

A. Both statement I and statement II are correct.

Step-by-step solution

- Statement I: The azimuthal quantum number (denoted as ( )) identifies the subshell and determines the shape of the orbital. This is correct. - Statement II: There are (2 +1 ) orbitals of each type in a subshell. This is also correct because for a given subshell with azimuthal quantum number ( ), the possible magnetic quantum numbers (m_ ) range from (- ) to (+ ), giving (2 +1 ) values, corresponding to the number of orbitals.
