any of a family (Dicruridae) of insectivorous passerine birds native to Africa, Asia, and Australia that usually have glossy black plumage and long forked tails.
There are four major types of compounds, distinguished by how the constituent atoms are bonded together. Molecular compounds are held together by covalent bonds; ionic compounds are held together by ionic bonds; intermetallic compounds are held together by metallic bonds; coordination complexes are held together by coordinate covalent bonds. Non-stoichiometric compounds form a disputed marginal case.
