Q. 4.67 - An Introduction to General, Organic, and Biological Chemistry

Question

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

Step-by-Step Solution

Answer

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

Step 1: Given Information

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

Step 2: 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 ${13}^{rd}$ group, Ge is in ${14}^{th}$ group and Br is in ${17}^{th}$ group.

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