Question 39
Arrange the following elements in the increasing order of their metallic character Mg, Ca, K, Ge, Ga

Answer 1

The correct order is Ge< Ga < Mg < Ca < K

Metallic character increases as one moves down the group because there is an increase in atomic size. As we move across the period the metallic character decreases as the there is an increase in nuclear charge and the atomic radius decreases too.
