Which of the following pair of elements have the same value of shielding constant for 3s electron??

a. Mn & Zn b. Fe & na c. Ar & Cl d. All of these

To find the shielding constant for 3s electron, we can follow the following rules:

  1. The remaining electrons in 3s contribute 0.35 to the shielding constant.
  2. The eectrons present in the (n-1)th shell contribute 0.85.
  3. All the electrons in the remaining inner shells coontribute 1.0 to shielding constant.

Using these rules calculate the hielding constant for the given pairs.

i think its Ar and Cl as they dont have much difference in their size.
