Carbon. Carbon.
Boron is the trace element in blue diamonds.
Carbon is the element found in diamonds, pencils (graphite), and is abundantly present in various forms on Earth.
Carbon is the main element in diamonds because it forms covalent bonds and a crystal lattice which is long chains of carbons that in turn form a very strong bond.
Diamonds are formed from the base element carbon, and so is coal. They are only related through their base element, and are not made from each other.
Diamonds are a form of crystalline carbon which is an element.
Diamonds are formed from carbon, which is the only element contained in diamonds, except for traces of other elements, such as nitrogen and boron. Trace elements can give colour to diamonds.
Coal and diamonds are both forms of carbon.
Diamonds are made of carbon.
Phosphorus is only present in a phosphorous but not in chitin so your answer is Phosphorus :)
Diamonds are made from carbon atoms arranged in a crystal lattice structure. Carbon is the only element that makes up diamonds, with each carbon atom forming strong covalent bonds with four neighboring carbon atoms, creating the hard and durable properties of diamonds.
Diamonds are single-element minerals composed entirely of carbon atoms.
There is only ONE element that makes diamonds. It is Carbon. Carbon has THREE(3) allotropes viz., Diamond, Graphite, and Buckminster Fullerene. An ALLOTROPE is were an element exhibits different physical characteristics.
