Q 4.95

Question: Arrange the following aspects from highest possible to lowest metallic character: S, Al, Cs, F, Sr, Cl


A. In order to resolve this problem, one must first know the metallic character boosts as friend go under a team in the periodic table, and also as you go left in ~ a duration on the routine table.

You are watching: Which element has the least metallic character

B. Then, in bespeak to determine the metallic character on each of the elements, you have to look at their ar on the routine table.

C. Since the question asks for the facets to be detailed in stimulate of diminish metallic character, it would certainly make more sense to uncover the element with the highest metallic personality first, then the 2nd highest, etc.

D. Dual check to make certain they room in the correct order and that you have actually not skipped any elements.

A. When moving from left to right, metallic personality decreases since the facets tend to gain electrons to to fill valence shells fairly than lose them. Elements on the right side, favor chlorine, will gain electrons to to fill their valence shells, while facets on the left side, favor cesium, will lose electrons in bespeak to have actually a full valence shell. When moving down the routine table, metallic character boosts because facets can shed electrons an ext easily as the atom radius increases. This is due to the fact that the attraction in between the nucleus and valence electron decreases together there is much more distance in between them.

B. traction up a regular table on a computer, or one that is in your beer-selection.comistry book. This is so the you have the right to visually compare where each element is in ~ on the routine table.

C. Look ~ above the bottom left side of the table and shot to locate some the the elements listed. Friend will view that cesium (Cs) and strontium (Sr) are placed on the bottom left side, so they will have the highest possible metallic characters. Cesium is farther under and an ext left 보다 strontium, therefore cesium will have actually the greatest metallic character and also strontium will have actually the 2nd highest metallic character. Next, girlfriend will see that aluminum (Al) is located farther left than sulfur, chlorine, and fluorine. This means that aluminum will be the aspect with the third highest metallic character. The only elements left space sulfur (S), chlorine (Cl), and also fluorine (F). They are all located within a very close street of one another. Sulfur is the farthest left and also farthest down of the three, so it will have actually the 4th highest metallic character. Chlorine is right below fluorine, making it the aspect with the fifth highest metallic character. This leaves fluorine together the critical element, definition it has actually the lowest metallic character.

We found cesium, strontium, aluminum, sulfur, chlorine, and fluorine on the periodic table. Cesium is the farthest left and the lowest, when fluorine is the the furthest right and also the highest, so we recognize they have the highest possible metallic character and also the shortest metallic character, respectively.

Answer: Cs, Sr, Al, S, Cl, F
