John Daltonís Periodic Tables
1803, the English school teacher and part-time scientist, John Dalton published
his first list of elements when he printed his atomic theory and his early gas
law work. †His original list showed only five
elements: hydrogen, oxygen, azote (nitrogen), carbon
and sulfur, along with their atomic weights. †
Daltonís First list of elements, published in 1803 with other work, contained only five elements, a far cry from the 100+ that we have today.
When the second volume of his work came out in 1827, the list of elements had grown to 36.† His symbols may look strange since they were not easy to remember and have not been used since the work was published.
