Jons jakobs berzelius: practical innovator; introduced rubber tubing, filter paper, and the modern chemical symbols: did chemical analysis to test law of multiple proportions gave analytical figures to. This s(cid:455)ste(cid:373) had o(cid:454)(cid:455)ge(cid:374)(cid:859)s ato(cid:373)i(cid:272) (cid:449)eight as 16 which led to less magnitude of error in measurement. His new table had o=100 and found the proportion of elements in each compound. Chose the symbol to be the 1st letter of the latin name and another if necessary as well as a numerical superscript to show the # of times the element showed.
