What is the name for elements that include properties of both metals and nonmetals?

Elements that exhibit properties of both metals and nonmetals are classified as metalloids. This unique group of elements typically possess a mix of physical and chemical characteristics, allowing them to display traits such as metallic luster while being brittle like nonmetals. They can conduct electricity better than nonmetals but not as well as metals, making them useful in various applications, particularly in semiconductors.

Metalloids are crucial in the development of electronic components and materials, bridging the gap between conductive and insulating materials. Their ability to form alloys with metals and compounds with nonmetals further highlights their dual nature.

Other classifications, such as nonmetals, noble gases, and transition metals, do not describe elements with mixed properties. Nonmetals generally lack metallic characteristics, noble gases have complete electron shells and are generally inert, and transition metals are known specifically for their metallic properties and complex electronic structures. Thus, metalloids stand out as the correct classification for elements with both metallic and nonmetallic traits.
