• # question_answer 48) Considering the elements, $B,Al,Mg$and K the correct order of their metallic character is: (a) B > Al > Mg > K (b) Al > Mg > B > K (c) Mg > Al > K > B (d) K > Mg > Al > B

(d) Metallic nature decreases in a period from left to right. Thus, $\underset{\xrightarrow[\text{in }\,\text{decreasing}\,\,\text{order}]{\text{Metallic}\,\text{nature}}}{\mathop{\text{K Mg Al}}}\,$ In a group, metallic nature increases from top to bottom. Thus, $Al\text{ }>\text{ }B$
