True

Vedclass · Answer

(A) The statement is True.$1$. Metallic character is the tendency of an element to lose electrons.$2$. Across a period,the effective nuclear charge increases,which pulls the valence electrons closer to the nucleus,making it harder to lose them; thus,metallic character decreases.$3$. Down a group,the number of shells increases,which decreases the effective nuclear charge experienced by valence electrons due to increased shielding,making it easier to lose electrons; thus,metallic character increases.

Write true or false for the statement: Metallic character decreases across a period and increases down a group because the effective nuclear charge acting on the valence shell electrons increases across a period and decreases down the group.
