semimetal
Neither metal nor nonmetal
A semimetal is an element with properties between metals and nonmetals—conducting electricity better than nonmetals but worse than true metals.
Silicon, germanium, and arsenic are semimetals, crucial to semiconductor technology.
Also called metalloid.
The term sometimes applies to metals with unusual electronic properties, like bismuth.
