Question

The screening effect of \( d \)-electrons is

• A. Equal to \( p \)-electrons
• B. Much more than \( p \)-electrons
• C. Same as \( f \)-electrons
• D. Less than \( p \)-electrons

Hint:

Electrons in the \( p \)-orbitals provide better shielding than \( d \)-electrons due to their higher probability of being closer to the nucleus.

Answer 1

The Correct Option is D

Step 1: Understand the concept of screening effect.
The screening effect refers to the ability of inner electrons to shield outer electrons from the attractive force of the nucleus.
Step 2: Conclusion.
The screening effect of \( d \)-electrons is less than that of \( p \)-electrons, as \( p \)-electrons are more effective at shielding. Final Answer: \[ \boxed{\text{Less than } p\text{-electrons}} \]
