C - Carbon

Although the name carbon comes from Roman times, the non-metallic element has been known, as charcoal, coal, diamonds and soot, since the dawn of mankind. More compounds known to us contain carbon than all the other elements combined, so naturally carbon compounds abound in our laboratory. Except for carbonates which were discovered in minerals, compounds that contain carbon are called organic compounds.
