Match each of the following descriptions to thecorrect element listed Pale yellow, odorless, brittle solid at room temperature, nonconductor
Silvery white, relatively soft, low density, conductive solid that is not found as a free element in nature but commonly found combined in alloys with copper or nickel
Metallic luster and grayish solid, very common in rocks and gemstones such as amethyst and opal, semiconductor
Not found as a free element (uncombined) in nature, reddish-brown liquid that vaporizes readily at room temperature to a red gas with a strong disagreeable odor
Silvery-white, ductile, malleable, conductive solid with a high melting point for this type of element
Colorless, tasteless, and odorless gas, unreactive, nonconductive.
Soft, easily cut with a knife to expose a silvery surface that rapidly oxidizes in air; never found uncombined in nature.
