In the second column from the ideal side of the regular table, you will find Group Seventeen (Group XVII). This column is the house of the halogen family of elements. Who is in this family? The facets included are fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At). What renders Them Similar?When girlfriend look at our descriptions of the aspects fluorine and also chlorine, you will watch that they both have actually seven electrons in their external shell. The seven-electron trait uses to all of the halogens. They space all simply one electron shy that having complete shells. Because they room so nearby to gift happy, they have the characteristics of combining with countless different elements. Castle are very reactive. You will certainly often find them bonding v metals and elements from group One of the regular table. The facets in the obelisk on the left each have actually one electron the they prefer 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 most reactive and combines through most aspects from around the routine table. Reactivity decreases as you relocate down the column. As you learn more about the table, you will uncover this sample true for other families. As the atom number increases, the atoms gain bigger. Their chemical properties change just a tiny bit when compared to the aspect right over them on the table.What is a Halide?The elements we are talking around in this ar are dubbed halogens. As soon as a halogen combine with another element, the resulting compound is dubbed a halide. One of the finest examples that a halide is salt chloride (NaCl). Don"t think the the halogens always make ionic compounds and salts. Part halides of the world are a component of molecules through covalent bonds.
