The semimetal/metalloid antimony (Sb) is not common in its native state.  It has a metallic luster, silvery-gray color, is somewhat soft (H=3 to 3.5), and is moderately heavy for its size.  Other semimetals that occur as native elements are arsenic (As) and bismuth (Bi).  The semimetals/metalloids resemble metals in luster, but they break along fractures - they’re brittle.  True metals are malleable.
