Vedclass · Answer

(A) Metallic character refers to the tendency of an element to lose electrons.In the periodic table,metallic character decreases as we move from left to right across a period because the effective nuclear charge increases,making it harder to lose electrons.All the given elements $(Na, Mg, Al, Si, Cl)$ belong to the $3^{rd}$ period of the periodic table.Their positions from left to right are: $Na$ (Group $1$),$Mg$ (Group $2$),$Al$ (Group $13$),$Si$ (Group $14$),and $Cl$ (Group $17$).Therefore,the order of decreasing metallic character is $Na > Mg > Al > Si > Cl$.

Arrange the following elements in the order of their decreasing metallic character: $Na, Si, Cl, Mg, Al$.
