Answer:
Jöns Jakob Berzellus _
<u>Invented the chemical notation system</u>
<u></u>
Explanation:
Meaning of chemical notation : It is the representation of chemical composition of element by symbols.
Berzelius was the first person to measure accurate atomic weight of the elements, which helped to confirm Dalton's Atomic Theory.
He described how chemical bonds are formed by electrostatic attraction.
Berzelius, work with atomic weight and his theory of electrochemical dualism led to the development of<u> Chemical notation that decide the chemical notation</u> of the compounds.This chemical notation determines about the element both qualitatively and quantitatively.
He identified that compounds can be distinguished by the opposing constituents which are the acidic constituent , the basic and the neutral part.
This formula representation is given by Berzelius.
