	Sulfur reacts with many metals. Electropositive metals give polysulfide salts. [[Copper]], [[zinc]] and [[silver]] are [[~~tarnished~~]] by sulfur. Although many [[sulfide mineral\|metal sulfides]] are known, most are prepared by high temperature reactions of the elements.{{Cite book \|last1=Vaughan \|first1=David J. \|title=Mineral chemistry of metal sulfides \|last2=Craig \|first2=James R. \|date=1978 \|publisher=Cambridge university press \|isbn=978-0-521-21489-6 \|series=Cambridge earth science series \|location=Cambridge London New york [etc.]}} Sulfide minerals contain the [[sulfide]] (S^2-) or [[disulfide]] (S₂^2-) anions.
