Question

The magnitude of shielding effect is dependent on_______.

• A. number of innermost electrons
• B. number of valence electrons
• C. number of protons in nucleus
• D. number of neutrons in nucleus

Answer 1

The correct option is A number of innermost electrons

In simple terms, shielding effect is defined as the protection given by the innermost electrons to valence electrons from nuclear charge. So more the number of innermost electrons the more will be the shielding effect.
