In the 2nd column from the right side that the routine table, you will find Group Seventeen (Group XVII). This pillar is the home of the halogen household of elements. That is in this family? The facets included room fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and also astatine (At). What renders Them Similar?When friend look at our explanation of the facets fluorine and also chlorine, you will view that they both have seven electron in their external shell. That seven-electron trait uses to all of the halogens. They space all simply one electron shy that having complete shells. Due to the fact that they space so nearby to being happy, they have the trait of combine with plenty of different elements. They are very reactive. You will often discover them bonding with metals and also elements from group One that the regular table. The elements in the shaft on the left each have actually one electron the they choose to donate.
We"ve just told you just how reactive the halogens are. Not all halogens react through the exact same intensity or enthusiasm. Fluorine is the most reactive and combines through most elements from approximately the regular table. Reactivity decreases together you move down the column. As you learn an ext about the table, friend will uncover this sample true for various other families. As the atom number increases, the atoms acquire bigger. Your chemical properties change just a tiny bit when compared to the facet right above them top top the table.What is a Halide?The facets we are talking about in this ar are called halogens. As soon as a halogen combine with an additional element, the resulting link is referred to as a halide. Among the finest examples that a halide is salt chloride (NaCl). Don"t think that the halogens always make ionic compounds and salts. Part halides of the people are a part of molecules through covalent bonds.

You are watching: The elements chlorine and iodine have similar chemical properties because they
