Carbon

It is a non metal!

Precautions

 * Pure carbon has extremely low toxicity to humans and can be handled and even ingested safely in the form of graphite or charcoal.
 * It is resistant to dissolution or chemical attack, even in the acidic contents of the digestive tract, for example
 * Consequently once it enters into the body's tissues it is likely to remain there indefinitely
 * However, inhalation of coal dust or soot (carbon black) in large quantities can be dangerous.
 * Carbon may also burn vigorously and brightly in the presence of air at high temperatures
 * Large accumulations of coal, which have remained inert for hundreds of millions of years in the absence of oxygen, may spontanesly combust when exposed to air
