Bismuth (Bi) appears to be a steel, but the volume of electrons readily available for electrical conduction is similar to that of semiconductors. Actually, bismuth is termed a semimetal. Molecular solids are often crystals shaped from molecules or polymers. They may be insulating, semiconducting, or metallic, according to the sort of molecules inside the crystal. New molecules are continuously getting synthesized, and several are made into crystals. The quantity of various crystals is big.
