How many orbitals is/are possible with n=3 , l=1 and m_l=-1 value?

Options

  1. A2
  2. B3
  3. C5
  4. D1

Correct answer

D. 1

Step-by-step solution

Symbol ' n ' represent number of shells. Symbol ' l ' represent value of subshell and symbol m_l represent value of orientation of the orbital. Given, n=3, l=1 and m_l=-1 means an orbital is present in p -subshell of 3rd shell having orientation value =-1 . (i.e. p_x or p_y ). Thus, only one orbital is possible for the given set of values of n, l and m_l . Hence, option (d) is the correct answer.
