Our word atom therefore comes from atomos, a Greek word meaning uncuttable. But the name stuck, and still has meaning in that atoms are the smallest, indivisible part of any element.
Who is responsible for the 200 year death of chemistry?
Death to the field of Chemistry for 2000 years! In the early 1800s, the English Chemist John Dalton performed a number of experiments that eventually led to the acceptance of the idea of atoms. He formulated the first atomic theory since the “death of chemistry” that occurred during the prior 2000 years.
