 
 <prompt> Which one of di following no be characteristic of intermetallic compounds: defined stoichiometry, bond types, or crystal structure? Given di previous question, write a context wey contain di answer. E fit be 1 - 20 sentences. Context: <response>: ```An alloy na mixture of metals or a mixture of metal and anoda element. Alloys dey defined by metallic bonding character. An alloy fit be solid solution of metal elements (a single phase) or a mixture of metallic phases (two or more solutions). Intermetallic compounds na alloys with defined stoichiometry and crystal structure. Zintl phases sometimes fit be alloys depending on bond types (see also: Van Arkel-Ketelaar triangle for information on classifying bonding in binary compounds).```
