23 ene 1770 año - At the time of Dalton's life, one of the best ideas about
atoms was Democritus'. Democritus lived in Greece
from around 460 BC to 370 BC. He was one of the
first people to think about atoms, and said that atoms
were the smallest particle in existence and that they
made up everything and were eternal and indestructible.
Atom comes from the Greek word 'atomos', meaning
'indestructible'.
