Mineral Species containing Carbon (C)

Element Properties, Isotopic Compositions for Carbon

**Carbon (C) Element Properties**
Atomic Mass	12.011
Atomic Number	6
Name Origins	Latin, carbo = "charcoal."
Year Discovered	Prehistoric
Discovery Credits	Known to prehistoric humans.
Remarks	Present as 4 allotropes. Used as coke (steel making), carbon black (printing), and activated charcoal (sugar refining, etc.). The radioactive isotope, C¹⁴, is produced in the atmosphere by cosmic ray bombardment of N¹⁴ and is not found in carbon-bearing minerals derived from atmospheric CO₂ older than 70,000 years. Diagnostic tests: As the carbonate (CO₃^2-), effloresces in dilute HCl with the evolution of colorless and odorless CO₂ gas. As the hydrocarbon, burns in air or O₂. As the element, carbon can be identified from physical properties (diamond, graphite). You can burn a diamond or graphite with difficulty by heating it to red heat in an O₂ atmosphere where it will leave none or very little residue.
