semimetals

Neither metal nor nonmetal

Semimetals are chemical elements with properties between metals and nonmetals.

They typically conduct electricity better than nonmetals but worse than metals, making them useful in electronics.

The term overlaps with metalloids, though usage varies among chemists.

Common examples include silicon, germanium, and arsenic: Semimetals are essential for semiconductor technology.
