Q. In a given shell, the order of screening effect is

Solution:

The electrons in the inner shells act as a screen of shield between the nucleus and the valence electrons in the outermost shell, known as the screening effect. The s-electrons have a greater probability of coming closer to the nucleus than the $p, d$ or $f$ electrons and hence the order of screening effect is $: s>p>d>f$
