Discover what metalloids are, where they are found on the periodic table, their properties, and everyday uses. Perfect resource for Chemistry students! What Is Metalloid? Metalloids are chemical elements that sit somewhere between the metal and non-metal classifications in terms of their chemical and physical properties. The seven most well-known metalloids are polonium, arsenic, tellurium, silicon, antimony, boron, and germanium. The standard periodic table shows that all seven of these elements are located in a diagonal section of the p-block that runs from astatine (located on the lower right) to boron (located on the upper left). The ... Learn what metalloids are, how they are positioned in the periodic table, and what properties and uses they have. Metalloids are elements with properties between metals and non-metals, such as boron, silicon, germanium, arsenic, and tellurium. Metalloids are often found along the "staircase" line on the periodic table, which separates the metals from the nonmetals . They are known for their brittle nature and semi-conductive properties, which are crucial in various technological applications such as electronics and optics.
