In addition to silicon, they include boron, germanium, arsenic, antimony, and tellurium. Metalloids fall between metals and nonmetals in the periodic table. Tellurium is a metalloid; it has a characteristic metallic luster, but can be pulverized to form a gray powder. The name of the element is derived from the Latin word for the Earth, tellus. It is found in the Earth's crust at a concentration of 5 ppb, making it the 72nd most abundant element. A metalloid is a chemical element that exhibits some properties of metals and some of nonmetals. In the periodic table metalloids form a jagged zone dividing elements that have clear metallic properties from elements that have clear nonmetallic properties.

Explain why the rest of the group has metallic behavior but boron does not. - 787841 It is a hard and brittle crystalline solid with a blue-grey metallic lustre; and it is a tetravalent metalloid and semiconductor. It is a lustrous, hard-brittle, grayish-white metalloid in the carbon group, chemically similar to its group neighbours silicon and tin. Arsenic is a metalloid.

Structures of the Metalloids. Covalent bonding is the key to the crystal structures of the metalloids. In this regard, these elements resemble nonmetals in their behavior. A metalloid is a chemical element that exhibits some properties of metals and some of nonmetals.

Learn more. Group 13. Group 13 contains the metalloid boron and the metals aluminum, gallium, indium, and thallium. The lightest element, boron, is semiconducting, and its binary compounds tend to be covalent and not ionic. The remaining elements of the group are metals, but their oxides and hydroxides change characters.
