Nature of Matter


   
 
Symbols of Elements
Even before knowing what elements were, man started extracting them from their ores. A few metals like gold, silver, iron, copper, lead, tin and mercury were used even in the 1st century A.D. A mention of them is made in the 'Charaka Samhita' - a medical treatise of ancient India. These metals were associated with a particular heavenly body.
 
 
Role of alchemists
 
Alchemists are the forerunners to the modern day chemists. Their quest was to convert base metals into gold using 'philosophers stone' an illusionary substance. Though unsuccessful on this front, they succeeded in separating and identifying arsenic, antimony and bismuth.
