Vedclass · Answer

(A) Metallic character is defined by the ease with which an element can lose electrons. Across a period from left to right,the effective nuclear charge increases and atomic size decreases,making it harder to lose electrons. Therefore,metallic character decreases across a period. For the given elements: $Na$ (Group $1$),$Mg$ (Group $2$),$Be$ (Group $2$),$Si$ (Group $14$),and $P$ (Group $15$). Comparing their positions: $Na$ is the most metallic,followed by $Mg$,then $Be$,then $Si$,and finally $P$ is the least metallic. The correct decreasing order is $Na > Mg > Be > Si > P$.

The correct decreasing order for metallic character is:
