Identify the orbital having lowest energy from following.

Options

  1. A2 p
  2. B3 s
  3. C3 d
  4. D4 p

Correct answer

A. 2 p

Step-by-step solution

The energy of an orbital in an atom depends on both the principal quantum number ((n) ) and the azimuthal quantum number ((l) ). According to the general trend, for orbitals with different principal quantum numbers, the one with the lower (n ) typically has lower energy. For orbitals with the same (n ), the one with the lower (l ) value will have lower energy. To identify the orbital with the lowest energy from the given options, consider: The principal quantum number ( (n )): ( aligned & 2p: n=2 & 3 ~s : n=3 & 3 ~
