Helium, titanium, selenium, palladium, promethium, cerium, europium, mercury, thorium, uranium, neptunium and plutonium are all given names connected to mythological characters. With some, that connection is indirect: europium: named for the continent that had been named after Europa.
William Odling. William Odling, FRS (5 September 1829 in Southwark, London – 17 February 1921 in Oxford) was an English chemist who contributed to the development of the periodic table. [1] In the 1860s Odling, like many chemists, was working towards classifying the elements, an effort that would eventually lead to the periodic table of elements.
Johan Erik Rydqvist. Baron Jöns Jacob Berzelius (Swedish: [jœns ˈjɑ̌ːkɔb bæˈʂěːlɪɵs] [1] (20 August 1779 – 7 August 1848) was a Swedish chemist. In general, he is considered the last person to know the whole field of chemistry. [2] Berzelius is considered, along with Robert Boyle, John Dalton, and Antoine Lavoisier, to be one of ...
The periodic table, also known as the periodic table of the elements, is an ordered arrangement of the chemical elements into rows (" periods ") and columns (" groups "). It is an icon of chemistry and is widely used in physics and other sciences. It is a depiction of the periodic law, which states that when the elements are arranged in order ...
List of chemical elements. 118 chemical elements have been identified and named officially by IUPAC. A chemical element, often simply called an element, is a type of atom which has a specific number of protons in its atomic nucleus (i.e., a specific atomic number, or Z). [1]
Edward G. Mazurs (1894–1983) was a chemist who wrote a history of the periodic system of the chemical elements which is still considered a "classic book on the history of the periodic table". [1] Originally self-published as Types of graphic representation of the periodic system of chemical elements (1957), it was reviewed by the ACS in 1958 ...
