Development of the Periodic table
The periodic table is a table of arrangement of chemical elements in order of atomic number. The table is organised in rows, so that elements with the similar atomic structure and similar chemical properties, appear in vertical columns.
Antoine Lavoisier was the first to write an extensive list of elements containing 33 elements and distinguished between metals and non-metals. He was scientist who is known as the “Father of Chemistry”. He named the elements carbon, hydrogen and oxygen, also discovered oxygen’s role in combustion and respiration, also established that water is a compound of hydrogen and oxygen. (1743-1794)
Jons Jacob Berzelius was a Swedish chemist. He was best known for his determination on atomic weight, chemical notation and isolation, and the discoveries of silicon, selenium, thorium and cerium, chemical elements.
One of Berzelius’s contributions to chemistry is the development of a system to symbolize chemical elements using letters like O for Oxygen, H for hydrogen and etc.
John Dalton was an English chemist, physicist and meteorologist. He is best known for proposing the modern atomic theory and Dalton’s Law. The “Dalton’s Law” describes the relationship between the components in mixture of gases. Daltons first list only consisted of five elements: hydrogen, oxygen, nitrogen, carbon and sulphur along with their atomic weights, compared to the one we have today with over a hundred elements.
Dmitri Mendeleev was passionate about chemistry; his deepest wish was to find a better way...
