Q 4.95

Question: Arrange the following facets from greatest to lowest metallic character: S, Al, Cs, F, Sr, Cl


A. In bespeak to deal with this problem, one must very first know that metallic character increases as girlfriend go down a team in the periodic table, and as you walk left within a period on the routine table.

You are watching: Which period 4 element has the most metallic properties

B. Then, in bespeak to identify the metallic personality on every of the elements, you have to look at their place on the periodic table.

C. Because the question asks for the aspects to be provided in order of to decrease metallic character, it would certainly make more sense to uncover the aspect with the greatest metallic character first, climate the 2nd highest, etc.

D. Double check to make sure they room in the exactly order and that you have not skipped any type of elements.

A. When relocating from left come right, metallic personality decreases because the aspects tend to obtain electrons to to fill valence shells quite than lose them. Facets on the best side, favor chlorine, will get electrons to to fill their valence shells, while aspects on the left side, like cesium, will lose electrons in bespeak to have actually a full valence shell. When relocating down the routine table, metallic character rises because elements can lose electrons more easily as the atom radius increases. This is since the attraction in between the nucleus and valence electron decreases together there is more distance between them.

B. traction up a routine table top top a computer, or one the is in your historicsweetsballroom.comistry book. This is so that you have the right to visually compare whereby each facet is in ~ on the periodic table.

C. Look ~ above the bottom left side of the table and try to situate some of the aspects listed. You will watch that cesium (Cs) and strontium (Sr) are placed on the bottom left side, therefore they will have the highest metallic characters. Cesium is farther down and much more left 보다 strontium, so cesium will have the greatest metallic character and strontium will have the second highest metallic character. Next, friend will view that aluminum (Al) is situated farther left than sulfur, chlorine, and fluorine. This way that aluminum will certainly be the element with the 3rd highest metallic character. The only elements left room sulfur (S), chlorine (Cl), and also fluorine (F). They room all located within a very close street of one another. Sulfur is the the furthest left and also farthest under of the three, so that will have the 4th highest metallic character. Chlorine is right listed below fluorine, making the the facet with the fifth highest metallic character. This pipeline fluorine together the last element, meaning it has the shortest metallic character.

We discovered cesium, strontium, aluminum, sulfur, chlorine, and fluorine ~ above the regular table. Cesium is the the furthest left and also the lowest, when fluorine is the farthest right and the highest, for this reason we know they have the greatest metallic character and also the shortest metallic character, respectively.

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