Our word atom therefore comes from atomos, a Greek word meaning uncuttable. ... In 1803, John Dalton formulated the "atomic theory" of matter based on experiments that quantified the weights of elements formed when compounds were broken down. Who created the human body? Andreas Vesalius was ...
Water, on the other hand, is not an element: a molecule of water consists of two hydrogen atoms (one proton each) sharing electrons with an oxygen atom (eight protons). Now, what does it mean to claim that an element "cannot be broken down into a simpler form," and why aren't ...
