definition A metalloid is a chemical element that has properties in between those of metals and nonmetals. There is no standard definition of a metalloid, nor is there complete agreement as to which elements are appropriately classified as such. Despite this lack of specificity, the term remains in use in chemistry literature. The six commonly recognised metalloids are boron, silicon, germanium, arsenic, antimony and tellurium. more like this
