Question

13. Which of the following element has highest shielding constant? (1) Mg (2) AI (3) K 4) Ga​

Answer 1

Answer:

(3).k....is correct I think

Answer 2

Answer:

(4) Ga

Step-by-step explanation:

Shielding constant ∝ atomic no. of electrons (more specifically no of electrons occupying shells other then the valence shell)

For a neutral atom, even more simply, more the atomic number, greater the shielding effect.

Here Gallium has the greatest atomic number, therefore greater shielding effect.
