About Jons

About

Jons Jakob Berzelius

Education/Future

Jons was born August 20th, 1779 in Östergötland, Sweden

but

unfortunately

died August 7th, 1848 in Stockholm, Sweden due to very poor health

He also attened Uppsala University in Sweden to continue his studies in chemistry which later led him to become one of the most famous chemists in the world because of his many contributions to the science.

Jons originally planned his future based on his plan to become a physician; however, his research in physical chemistry led him to the many contributions he made for chemistry today.

He was especially determined and known for his dedication for atomic weights

because of these interests, this led to more information about the pricipals of stoichimerty

a.k.a.

the fieldof chemical bonding proportions

First Discoveries

Berzelius's work with atomic weights and his theory of electrochemical dualism led to his development of the modern system known today as chemical formula notation.

This formula was meant to show/explain the composition of any compound both qualitatively (by showing its electrochemical ingredients) and quantitatively (by showing the proportions in which the ingredients were united).

Jons was so interested in his studies that he even convinced a professor at his University to allow him access to the laboritory after hours.

Second Discovery

Berzelius has also discovered and isolated several new elements, including cerium in 1803 and thorium in 1828 due to his deep interest in mineralogy.

Example of this contribution:

Jons and a colleague known as Johan Gottlieb Gahn noticed an unusual substance while studying a method of producing sulfuric acid. At first they thought the substance was tellurium; however, after careful quantitative analysis, they realized that they had doscovered a new element and later on named it selenium.

Main Contribution

Jons most important/famous contribution to modern day chemistry was his developement of a rational system of atomic symbols.

Most of these symbols simply came from the first letter of the elements name; however, first letters of elements would repeat due to the wide variety which forced Jons to use Latin as another way to name elements.

Example: Silver and Gold - silver is knowns as argentum in latin and gold is known as aurum which is how they got their atomic names as Ag and Au.

Along with this famous discovery of his, he also decided to add algebraic exponents (later became subscripts) to compounds

Ag

Au
