He additionally published several books including “Elementary Treatise of Chemistry” which is known as the first modern Chemistry textbook. While his textbook did have a few errors it made important advancements such as defining a chemical element as a substance that cannot be reduced in weight by a chemical reaction. Not only did he make these discoveries and observations but he also assisted in creating the metric …show more content…
Later on he would create a book called A New System of Chemical Philosophy, this book Dalton’s theory that elements are identifiable by their atomic weight. In addition Dalton discovered that atoms couldn’t be created or destroyed.
The last influential chemist is Dmitri Mendeleev. Dmitri Mendeleev was a chemist in the 19th century. Dmitri Mendeleev is known for creating the first periodic table of elements. He set the table up in order of atomic mass. When the elements were set up in this style similar elements could be grouped together to show they had similar properties. Since this table was created in the 19th century not all elements were discovered, leaving Mendeleev to leave spaces in the table to later be
