AS the Society is aware, the first table, containing the relative weights of the ultimate particles of gaseous and other bodies, was published as the eighth and last paragraph to a paper by Dalton ...

Two hundred years ago today, British chemist John Dalton helped turn chemistry into an exact science. He presented his Table of Atomic Weights at the Manchester Literary and Philosophical Society ...

1803 John Dalton (left), an English schoolteacher, compiles the first table of atomic weights for various elements, using units where the atomic weight of hydrogen was equal to 1.

The atomic weight thus assumes the role of a secondary characteristic; the important property of any element is its nuclear charge, so that by arranging the elements in order of increasing nuclear ...

Visual representation John Dalton's list of atomic weights and symbols. Photo: Wikimedia Commons One of the first things we learn in chemistry are atomic symbols to represent different elements.

But, as is well known, the state of knowledge in Dalton's day was not sufficiently advanced to enable him to attribute to elements their correct relative atomic weights; and it was not until the ...
