In the 2nd column indigenous the ideal side that the routine table, girlfriend will uncover Group Seventeen (Group XVII). This pillar is the house of the halogen family of elements. Who is in this family? The elements included are fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At). What makes Them Similar?When girlfriend look at our explanation of the aspects fluorine and chlorine, you will check out that they both have seven electron in their outer shell. The seven-electron trait uses to all of the halogens. They room all just one electron shy that having complete shells. Due to the fact that they room so nearby to gift happy, they have actually the characteristics of combining with plenty of different elements. Castle are an extremely reactive. You will certainly often uncover them bonding v metals and also elements from team One of the periodic table. The aspects in the tower on the left each have one electron that they choose to donate.
We"ve just told you just how reactive the halogens are. No all halogens react through the very same intensity or enthusiasm. Fluorine is the many reactive and also combines through most elements from roughly the periodic table. Reactivity decreases together you relocate down the column. As you learn an ext about the table, you will find this sample true for various other families. As the atomic number increases, the atoms acquire bigger. Your chemical properties readjust just a small bit when compared to the aspect right above them top top the table.What is a Halide?The elements we are talking about in this section are dubbed halogens. As soon as a halogen combines with another element, the resulting compound is referred to as a halide. Among the ideal examples of a halide is sodium chloride (NaCl). Don"t think that the halogens constantly make ionic compounds and also salts. Part halides the the world are a component of molecules with covalent bonds.
