What is a metalloid?
ChemistryPeriodic table
Quick Answer
A metalloid is an element with properties between metals and nonmetals. Common metalloids include silicon and germanium.
The Full Story
Metalloids sit along a diagonal “stair-step” region of the periodic table and often show mixed behavior. They may look metallic but conduct electricity only moderately, which is why some are important in electronics. Silicon is the most famous metalloid because it is the foundation of modern semiconductors and computer chips. The term is used with some flexibility, but it remains a helpful way to classify elements with intermediate properties. Their unique behavior makes them valuable in technology and materials science.
