Who invinted symbols for stuff like water and air?
Huh? I didn’t know there was a symbol for air. If you are asking about the symbols for the elements of the periodic table, the answer could be several different scientists. The first to use any kind of symbol for an element was Dalton in 1808. He was followed by Berzelius in 1813. He was the first to use the form of symbols that we use today. Next there were seven men who presented proposals of arrangements of the elements in a table. Then Mendeleev presented his arrangement in 1869. As a result of the work of Henry Moseley in 1913, the periodic table was revised. If you are asking about the symbols in the periodic table, then Berzelius is your guy.
