A certain orbital has no angular nodes and two radial nodes. The orbital is :

  1. A 2s
  2. B 3s Correct answer
  3. C 3p
  4. D 2p

Solution

Angular nodes = $\ell$ = 0<br><br> Radial nodes $\Rightarrow$ (n – $\ell$ – 1) = 2<br> $\Rightarrow$ n – 0 – 1 = 2<br> $\Rightarrow$ n = 3<br><br> So orbital is 3s.
