 * Antimony (Sb)
 * Tellurium (Te)
 * Polonium (Po)
 * Astatine (At)

Physical Properties of Metalloids

Chemical Properties of Metalloids ==== The chemical properties of metalloids are that they act like non-metals when they are reacting with metals and they act like metals when they are reacting with metals. The conductivity of metalloids are affected by temperature, light exposure or small impurities. ====

Interesting Facts 1.Silicon is the second most common element on the Earth's surface. 2.Some of the metalloids do not conduct heat or electricity. An example is Arsenic. 3. The boiling points, melting points, an ddensity very widely.

Uses of Metalloids Metalloids are used as microchips in things like computers and calculaters. They are also used to make semiconductors. Semiconductors are used to turn electric currents on and off.
