This process allows the stone to take a high polish. This stone is generally formed when limestone is faced with extremes of pressure or temperature that cause it to undergo a process known as metamorphism. When Metamorphism occurs the structure of the limestone becomes crystal in nature, transforming into calcite or dolomite. These two substances are the main materials in marble. The crystal is a very strong molecular form and the result of this is a strongerChromium is steel gray,lustrous,hard,metallic and takes a high polish.İt compounds are toxic.İt is found as chromite ore.siberion red lead(crocoite,PrCrO4)is a chromium ore prized as a red pigment for oil paint.For each compound and where possible a formal oxidation number for each element is given but the usefulness of this number is limited,especially so for p-block elements in particular.Based upon that oxidation number an electronic configuration is also given but note thatfor more exotic compounds you should view this as a guide only(Cr2O3). This section lists some binary compounds with halogens (known as halides), oxygen (known as oxides), hydrogen (known as hydrides), and some other compounds of chromium. For each compound, a formal oxidation number for chromium is given
