Diamonds are an allotrope of carbon, as is coal. An "Allotrope" implies a different bonding structure in coal than is in diamond. Carbon is the element common to both. Many people think of diamonds as coal that was compressed over millions of years and tonnes of pressure generated from the earth's repeated deposits of layers of soil and sediment onto layers deposited previously over vast periods of time.Mines run deep into the earth: in some places mines cut miles below the surface of the earth at a given location.
Inclusions in diamond material are often small particles of carbon almost invisible to the naked eye but easily seen under 10x magnification- or with a jeweller's loupe ( graded diamonds are based on the quality or clarity of the diamond material as well as colour, and cut if it is a faceted stone used most commonly in jewellery). The more included a diamond is - or the higher the number of particles of carbon it contains- the lower its value.
Diamond is a particular elemental compound composed of carbon.
Diamond is a compound of carbon and does not combine, except minutely with other elements. Other elements can give diamond a subtle colour.
coal, carbons. Formed by intense pressure.
Diamonds are Carbon; that's it. Coal is mostly Carbon with other elements in it.
Crystals can be elements (as diamond) or compounds (as sapphire).
Crystals can be elements (as diamond) or compounds (as sapphire).
No. coal is coal and diamond is diamond. They are both formed from carbon, but diamond is much harder than coal.
Diamond and graphite are both forms of the element carbon. They are not compounds, because a compound by definition involves the combination of two or more different elements.
compound
Yes....it is an element....it is an isotope...(isotope) meaning two or more forms of the same element whose atoms differ in number of neutrons... hence in mass. Example C - Carbon = Coal = Diamond -- diamond is the purest form of carbon
Yes. Both diamond and coal are formed from carbon.
Technically, diamond is neither an element, a compound, or a mixture. Diamond is made up of pure carbon atoms, so it is not a mixture, and a compound by definition requires two or more different elements. The best definition using the above terms is that diamond is a mineral made up of the same element.
