You can call it as the first use of symbols for representing the elements associated with modern chemistry. Later on, he managed to prepare a table comprising of 21 elements which were arranged by atomic mass. This idea was sooner published in a scientific paper. WebOct 13, 2024 · Atoms of one element can combine with atoms of different elements to make compounds. Dalton was able to predict the formation of multiple compounds between the elements by picturing compounds as collections of atoms and then considering how these atoms could combine to form more than one compound. how to skateboard distance
