Question: Arrange the adhering to elements from highest to lowest metallic character: S, Al, Cs, F, Sr, Cl
A. In order to deal with this difficulty, one need to first understand that metallic character boosts as you go dvery own a group in the periodic table, and also as you go left within a period on the routine table.
You are watching: Which of the following elements has the greatest metallic character?
B. Then, in order to identify the metallic character on each of the aspects, you have to look at their place on the routine table.
C. Because the question asks for the aspects to be listed in order of decreasing metallic character, it would certainly make even more sense to discover the facet via the highest possible metallic character first, then the second highest possible, and so on.
D. Double inspect to make certain they are in the correct order and that you have not skipped any facets.
A. When relocating from left to appropriate, metallic character decreases because the facets tend to get electrons to fill valence shells quite than lose them. Elements on the appropriate side, prefer chlorine, will get electrons to fill their valence shells, while elements on the left side, choose cesium, will lose electrons in order to have actually a complete valence shell. When relocating dvery own the regular table, metallic character increases bereason aspects deserve to lose electrons even more conveniently as the atomic radius boosts. This is because the attraction in between the nucleus and also valence electrons decreases as tbelow is more distance between them.
B. Pull up a regular table on a computer, or one that is in your tasiilaq.netisattempt book. This is so that you can visually compare wright here each facet is at on the routine table.
C. Look on the bottom left side of the table and also attempt to situate some of the aspects detailed. You will watch that cesium (Cs) and strontium (Sr) are put on the bottom left side, so they will have actually the greatest metallic personalities. Cesium is farther dvery own and also more left than strontium, so cesium will certainly have the highest possible metallic character and also strontium will certainly have the second greatest metallic character. Next, you will view that aluminum (Al) is situated farther left than sulhair, chlorine, and also fluorine. This indicates that aluminum will be the element through the third greatest metallic character. The only facets left are sulhair (S), chlorine (Cl), and also fluorine (F). They are all located within an extremely cshed distance of one another. Sulfur is the farthest left and farthest down of the 3, so it will certainly have the fourth highest metallic character. Chlorine is best below fluorine, making it the aspect with the fifth highest possible metallic character. This leaves fluorine as the last aspect, meaning it has actually the lowest metallic character.

We found cesium, strontium, aluminum, sulhair, chlorine, and also fluorine on the routine table. Cesium is the farthest left and the lowest, while fluorine is the farthest appropriate and the greatest, so we understand they have the greatest metallic character and also the lowest metallic character, respectively.
