Solution:
The above statement is false.The increasing order of metallic character of the given element is Ga< Ge< Mg< K< Ca.
The metallic character of an element is the ability of an element by which it can donate electrons to other atoms, just like metals top from bottom in the periodic table and are electropositive. Therefore, Metallic properties increases down the group as the size of an atom increases, which leads to lesser attraction between the nuclei and the electrons. Thus the outermost electrons of a metallic atom are loosely bound.
The corrected statement would be, “Increasing order of metallic character Ge< Ga< Mg< Ca< K”.
