Solution: In which of the following atoms is the 2s orbital closest to the nucleus?A) SB) ClC) PD) SiE) The 2s orbitals are the same distance from the nucleus in all of these atoms.

Problem

In which of the following atoms is the 2s orbital closest to the nucleus?

A) S

B) Cl

C) P

D) Si

E) The 2s orbitals are the same distance from the nucleus in all of these atoms.

Solution

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

  • The 2s 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 2s orbital will be.
