Q:

What are metalloids?

A:

Metalloids are chemical elements that have properties common with both metals and nonmetals. Some metalloid semiconductors are able to carry an electrical charge under the right conditions, a property that allows them to be used in the production of computers and other electronic devices.

Chemical elements can be classified as either metal or nonmetal, depending on the various physical and chemical properties they possess. Metalloids such as boron, silicon and arsenic possess mixed properties that make them harder to characterize. While there is no rigorous definition for the term, chemical elements that form amphoteric oxides or that possess semiconductor properties are often considered metalloids.

  • Q:

    How are metalloids used in our everyday life?

    A:

    Metalloids are used very commonly in solid-state electronics, as components of alloys in metal objects, in glass and in flame- and heat-resistant objects. Metalloids in their pure forms are too brittle to be used in tools or in structural applications.

  • Q:

    What are transition metals?

    A:

    Transition metals refer to the 38 elements from groups three to 12 on the periodic table. They are hard, ductile, malleable and capable of conducting heat and electricity. They often have several common oxidation states, because their valence electrons exist in more than one shell.
