| Carbon | |
You are carbon. Carbon takes many forms. You see pure carbon as the toner in your printer (carbon black), as diamonds, and as the 'lead' in your pencil (graphite). Carbon is found in all living cells. It participates in many chemical reactions. This non-metallic element has been known since prehistoric time. Some people consider it to be a ho-hum boring element, yet others value it for its countless uses.
