Barone Jöns Jacob Berzelius è stato un chimico svedese. Berzelius è considerato, insieme a Robert Boyle, John Dalton e Antoine Lavoisier, uno dei fondatori della chimica moderna. Divenne membro dell'Accademia reale svedese delle scienze nel 1808 e dal 1818 fu il suo principale funzionario. È conosciuto in Svezia come il "padre della chimica svedese". Il 20 agosto si celebra il "Berzelius Day" in suo onore. Sebbene Berzelius avesse iniziato la sua carriera come medico, i suoi contributi

Andriiko1 · Hans‑Joachim Lunk2 Received: 24 January 2018 / Accepted: 12 February 2018 Ranked between metals and non-metals in the periodic table, silicon (Si) belongs to the metalloids family. Silicon is the most abundant element in the Earth's crust after oxygen (O) but it does not naturally exist in a free state on Earth. Commonly found in the form of oxides, it is one of the main components of clay, granite, quartz and sand.

Jöns Jacob Berzelius. University of Nottingham: The Periodic What was Jons Jacob Berzelius's contribution to the periodic table? In 1828, he proposed symbols to be used to represent the elements. (Symbols were based on the elements Latin names, and they're still used today.) The term "electronegativity" was introduced by Jöns Jacob Berzelius in 1811, though the concept was known before that and was studied by many chemists including Avogadro.

Berzelius was a Swedish chemist. In 1828 he compiled a table of relative atomic weights, where oxygen was set to 100, and which included all of the elements known at the time. Of significance for the periodic table is that he invented the modern system of chemical notation and established the basic symbols for the elements as used today. The next step in preparing the way for the Periodic Table was the development of exact analytical methods to give precise atomic weights. Swedish chemist Jöns Jacob Berzelius (1779-1848) is widely credited with establishing several of these standard methods, while raising the sophistication of laboratory chemistry to new heights during the first half of the nineteenth century. Berzelius is credited with discovering the chemical elements cerium and selenium and with being the first to isolate silicon and thorium.
