Ethers (R−O−R) consist of an oxygen atom between the two attached carbon chains. The shorter of the two chains becomes the first part of the name with the -ane suffix changed to -oxy, and the longer alkane chain becomes the suffix of the name of the ether. Thus, CH 3 OCH 3 is methoxymethane, and CH 3 OCH 2 CH 3 is methoxyethane (not ...
The main structure of chemical names according to IUPAC nomenclature. The International Union of Pure and Applied Chemistry (IUPAC) has published four sets of rules to standardize chemical nomenclature. There are two main areas: IUPAC nomenclature of inorganic chemistry (Red Book) IUPAC nomenclature of organic chemistry (Blue Book)
Hydrides of the main group elements (groups 13–17) are given the base name ending with -ane, e.g. borane (B H 3), oxidane (H 2 O), phosphane (P H 3) (Although the name phosphine is also in common use, it is not recommended by IUPAC). The compound P Cl 3 would thus be named substitutively as trichlorophosphane (with chlorine "substituting ...

Proposed name for seaborgium. The symbol and name were instead used for element 104. [nb 1] [nb 3] [5] Ro: Rhodium: 45: Current symbol is Rh. [nb 1] Sa: Samarium: 62: Current symbol is Sm. [nb 1] [5] So: Sodium: 11: Current symbol is Na. [nb 1] Sq: Sequanium: 93: Discredited claim to discovery of neptunium made by Horia Hulubei and Yvette ...
Elements that have not been given trivial names by IUPAC may be referred to either by IUPAC systematic element names and symbols, or by atomic numbers. So ununennium and element 119 are both correct, and symbols Uue , 119 , E119 may all be used in text.
This list is sorted by boiling point of gases in ascending order, but can be sorted on different values. "sub" and "triple" refer to the sublimation point and the triple point, which are given in the case of a substance that sublimes at 1 atm; "dec" refers to decomposition. "~" means approximately.
The first letter is always capitalized. While the symbol is often a contraction of the element's name, it may sometimes not match the element's English name; for example, "Pb" for lead (from Latin plumbum) or "W" for tungsten (from German Wolfram). Elements which have only temporary systematic names are given temporary three-letter symbols (e.g ...
