Given below are two statements: Statement I: The principal quantum number determines the shape of the orbital. Statement II: The magnetic orbital quantum number determines the orientation of the orbital in space. 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 incorrect but Statement II is correct
  3. CStatement I is correct but Statement II is incorrect
  4. DBoth Statement I and Statement II are incorrect

Correct answer

B. Statement I is incorrect but Statement II is correct

Step-by-step solution

Statement I is incorrect because the principal quantum number ( n ) determines the size and energy of the orbital, whereas the azimuthal quantum number ( l ) determines the shape of the orbital. Statement II is correct because the magnetic orbital quantum number ( m_l ) determines the orientation of the orbital in space. Answer: Statement I is incorrect but Statement II is correct
