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. chrome pc indir

"WebMay 14, 2016 · Explanation: Shielding is when electrons in the inner electron shells of an atom can shield the outer electrons from the pull of the nucleus. The nucleus can pull the outer electrons in tighter when the attraction is strong and less tight when the attraction is weakened. Therefore, the more shielding that occurs, the less attraction there is ... " - Poor shielding effect means
