Organize the following metals from least metallic to most metallic: barium, zinc, iron, and strontium.

the answer is: zinc, iron, strontium, barium

Explanation:

In a period, there will be decrease in metallic character of elements on moving from left to right in a periodic table. This is because size of elements decreases on moving from left to right.

Hence, ability to lose the electron also decreases. Therefore, decrease in metallic character occurs.

Whereas, in a group there will be increase in size of elements on moving downwards. Hence, more is the size of element more easily it is able to lose the valence electrons.

As a result, more will be its metallic character.

Thus, we can conclude that the metals from least metallic to most metallic are as follows.

                                Zn < Fe < Sr < Ba
