Answer» Gold and Platinum are the two metals that occur in the free or native state. The metallic compounds which occur in : 1. Halides – Cryolite[Na₃AlF₆ ], Flurospar[CaF₂ ], Rock Salt[NaCl] 2. Oxides – Bauxite[Al₂O₃ .2H₂O], Zincite[ZnO], Cuprite[Cu₂O] 3. Sulphides – Iron Pyrite[FeS₂ ], Zinc blende[ZnS], Gdlena[PbS]
