Arrange the following elements in the order of their decreasing metallic character:
(A) Cl > Si > Al > Mg > Na
(B) Na . Mg > Al > Si > Cl
(C) Na > Al > Mg > Cl > Si
(D) Al > Na > Si > Ca > Mg
Arrange the following elements in the order of their decreasing metallic character:
(A) Cl > Si > Al > Mg > Na
(B) Na . Mg > Al > Si > Cl
(C) Na > Al > Mg > Cl > Si
(D) Al > Na > Si > Ca > Mg
(B) Na . Mg > Al > Si > Cl
B is the correct answer = Na > Mg > Al > Si > Cl. Along the period, metallic character decreases, all elements belong to period-3.
