Individual lists share common ground, with variations occurring at the margins. It is located in Group 17 of the periodic table, which is also known as the halogens group. These elements have metallic character, which means atoms easily lose electrons. These classifications are based on shared physical Directions: Using your Periodic Table of Elements, place the following elements into their appropriate Class (Metals, Metalloids, Non-Metals). Silicon, the most well-known metalloid, looks shiny like a metal but is brittle and conducts electricity only under certain conditions, making it a semiconductor. They’re lustrous, but they’re brittle, like iodine and tellurium. Silicon is used extensively in computer chips and other electronics because its electrical conductivity is in between that of a metal and a nonmetal. No, iodine is not a metal. As a non-metal, iodine shares some common characteristics with other non-metals in this group, such as fluorine, chlorine, and bromine. Metallic Character comes from an element’s tendency to lose electrons and form positive ions (cations). Metalloids can also be called semimetals. Groups are numbered 1–18 from left to right. Boron, silicon, germanium, arsenic, tellurium, and antimony are some commonly known metalloids. They range from colorless gases like hydrogen to shiny crystals like iodine.
