Descrizione:

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.
Dalton theorized that all matter is made of atoms an that atoms are too small to see, "uncuttable," and indestructible. He also theorized that all atoms of a given element are exactly alike and atoms of different elements are different.
