Chapter 1 Minerals Flashcards | Quizlet

Mineral deposit, aggregate of a mineral in an unusually high concentration. About half of the known chemical elements possess some metallic properties. The term metal, however, is reserved for those chemical elements that possess two or more of the characteristic physical properties of metals (opacity, ductility, malleability, fusibility) and are also good conductors of heat and electricity.
