“What’s a metalloid?”

When browsing through the periodic table, you might see a group of elements that have a very strange description called metalloids. In short, metalloids are elements that have properties of both metals and non-metals. The elements that make up the metalloid group include boron [B], Silicon [Si], Germanium [Ge], Arsenic [As], Antimony [Sb], Tellurium [Te], Polonium [Po], and Astatine [At]. These elements are typically very brittle and have a fair amount of electrical conductivity. What makes metalloids especially interesting is that some of them (such as Germanium and silicon) have the properties of being semiconductors.
