WebNo Comments. The screening effect of d- electrons is less than p – electrons. In general, d and f electrons have a poor shielding effect compared to s and p electrons. This is because s and p electrons are close to the nucleus whereas d and f electrons are more diffused (away from the nucleus). Hence, the correct option is D. WebThe screening or shielding effect: When the number of inner electrons is greater, they shelter the outermost electron from the nucleus, allowing it to neglect the nuclear pull to some extent. This is referred to as the shielding or screening effect.
