The properties of metalloids are between metals and nonmetals.
Generally, metalloids behave as nonmetals, both chemically and physically.
But their electrical conductivity resmeble metals.
They are semiconductors.
They conduct electricity, but not as well as metals.
This property, particularly found in silicon and germanium, is responsible for the remarkable progress in the field of solid-state electronics.
Transistors in electronics today are made from semiconductors.
They have reduced the size of electronic components to an almost microscopic level--basicall a microcircuit printed on a tiny silicon chip.
