We are being asked which of the following atoms is the 2s orbital closest to the nucleus. 

  • The 3s orbital distance from the radius will differ depending on the number of protons in the nucleus.
  • So we know that option e is already false. 
  • Effectively, the smaller the atomic radius, the closer the 3s orbital will be.
