Find the exact orbital from the following for which (n=4 ) and (l=1 ).

Options

  1. A(4 s )
  2. B(3 d )
  3. C(4 d )
  4. D(4 p )

Correct answer

D. (4 p )

Step-by-step solution

For, (n ) (principal quantum number) (=4 ) and (l ) (azimuthal quantum number) (=1 ) The orbital is (4 p ). For, ( aligned & 4 s n=4, l=0 & 3 d n=3, l=2 & 4 d n=4, l=2 aligned )
