Question

Screening of the nuclear charge by core electrons in atoms is __________. screening of the nuclear charge by core electrons in atoms is __________. less efficient than that by valence electrons responsible for a general decrease in atomic radius going down a group essentially identical to that by valence electrons more efficient than that by valence electrons both essentially identical to that by valence electrons and responsible for a general decrease in atomic radius going down a group

Answer 1

The screening of the nuclear charge by core electrons in atoms IS MORE EFFICIENT THAN THAT BY VALENCE ELECTRON.
Screening effect refers to the reduction in the effective nuclear charge on the electron cloud due to a difference in the attraction forces of the electrons on the nucleus.<span />
