Question

Place the following in order of decreasing metallic character: Br, Ge, Ca, Ga.

Short answer

The correct order is Ca, Ga, Ge, Br.

Step-by-step solution

Given Information

We have to place the elements Br, Ga, Ge, Ca in correct order of property metallic character.

Explanation

As metallic character decreases as we move left to right and increases down to group and all the metals given are in $4^{th}$period but their groups are different.

Ca is in $2^{nd}$group, Ga is in role="math" localid="1651895263289" ${13}^{rd}$group, Ge is in role="math" localid="1651895256538" ${14}^{th}$group and Br is in ${17}^{th}$group.

This states that the correct order is Ca, Ga, Ge, Br.
