Question: Arrange the following aspects from highest to lowest metallic character: S, Al, Cs, F, Sr, Cl
A. In bespeak to settle this problem, one must very first know that metallic character rises as you go down a group in the regular table, and as you go left within a duration on the regular table.

B. Then, in order to identify the metallic character on every of the elements, you have to look in ~ their ar on the routine table.
C. Since the question asks for the facets to be listed in stimulate of to decrease metallic character, it would make more sense to find the element with the highest metallic character first, climate the 2nd highest, etc.
D. Dual check come make certain they room in the correct order and also that you have actually not skipped any kind of elements.
A. When relocating from left to right, metallic character decreases due to the fact that the facets tend to get electrons to to fill valence shells quite than lose them. Facets on the right side, prefer chlorine, will gain electrons to fill their valence shells, while elements on the left side, prefer cesium, will shed electrons in order to have actually a full valence shell. When relocating down the regular table, metallic character boosts because facets can shed electrons an ext easily together the atomic radius increases. This is because the attraction between the nucleus and also valence electron decreases together there is much more distance between them.
B. traction up a routine table ~ above a computer, or one the is in her gaianation.netistry book. This is so the you have the right to visually compare wherein each element is at on the regular table.
C. Look top top the bottom left next of the table and try to find some of the facets listed. You will see that cesium (Cs) and also strontium (Sr) are inserted on the bottom left side, for this reason they will have actually the highest metallic characters. Cesium is farther under and much more left 보다 strontium, for this reason cesium will have the highest possible metallic character and also strontium will have actually the second highest metallic character. Next, you will check out that aluminum (Al) is located farther left than sulfur, chlorine, and also fluorine. This means that aluminum will certainly be the facet with the third highest metallic character. The only elements left room sulfur (S), chlorine (Cl), and also fluorine (F). They are all located within a really close street of one another. Sulfur is the farthest left and farthest down of the three, so the will have actually the fourth highest metallic character. Chlorine is right listed below fluorine, making it the element with the fifth highest metallic character. This pipeline fluorine together the critical element, definition it has the lowest metallic character.

We discovered cesium, strontium, aluminum, sulfur, chlorine, and also fluorine top top the routine table. Cesium is the the furthest left and also the lowest, when fluorine is the farthest right and also the highest, for this reason we know they have the highest metallic character and the shortest metallic character, respectively.
Answer: Cs, Sr, Al, S, Cl, F
