The prefix “thio” indicates the presence of which chemical element?
Thio- of oxygen to sulfur is called thionation or thiation. Thio- can be prefixed with di- and tri- in chemical nomenclature. The word derives from Greek "theîon" = "sulfur" (which occurs in Greek epic poetry as "théweion" and may come from the same root as Latin "fumus" (Indo-European "dh-w") and may have originally meant "fumigation substance".) Thio- The prefix thio-, when applied to a chemical, such as an ion, means that an oxygen atom in the compound has been replaced by a sulfur atom. This term is often used in organic chemistry. For example, from the word "ether," referring to an
Chemical element February 2010. The heaviest element that is believed to have been synthesized to date is element 118, oganesson, on 9 October 2006, by the Flerov Laboratory of Nuclear Reactions in Dubna, Russia. Tennessine, element 117 was the latest element claimed to be discovered, in 2009. On 28 November 2016, scientists at the IUPAC officially recognized the names for four of the newest chemical elements, with atomic numbers 113, 115, 117, and 118. The following sortable table shows the 118 known chemical elements. Chemical element A chemical element is a species of atoms having the same number of protons in their
