Vedclass · Answer

(C) Metallic character increases down a group and decreases across a period from left to right.$K$ (Potassium) is in Group $1$ and Period $4$.$Ca$ (Calcium) is in Group $2$ and Period $4$.$Be$ (Beryllium) is in Group $2$ and Period $2$.Comparing these,$K$ is the most metallic as it is in Group $1$. Between $Ca$ and $Be$,$Ca$ is more metallic because it is below $Be$ in Group $2$.Therefore,the correct order is $K > Ca > Be$.
