by WebElements: the periodic table on the web

A panel commentary in Nature Chemistry Commentary speculates upon the names that might be proposed for the four new elements in the periodic table. Worth a read, but we’ll have to wait a while longer yet.

Abstract: “Of all the things humans can bestow names upon, new chemical elements are about the rarest. Our group of periodic table experts attempts to read the tea leaves and predict the names for elements 113, 115, 117 and 118.”

The International Union of Pure and Applied Chemistry (IUPAC) has provisional recommendations for the naming of new elements and the recommendations are open for comment until 29 February 2016.

IUPAC state “the most important change is that the names of all new elements should have an ending that reflects and maintains historical and chemical consistency. This would be in general “-ium” for elements belonging to groups 1-16, “-ine” for elements of group 17 and “-on” for elements of group 18.”

The discoverers have the right to suggest names and symbols.

The International Union of Pure and Applied Chemistry (IUPAC) announced IN January 2016 that the identification of the four new elements with atomic numbers 113, 115, 117, and 118 is verified and that the discoverers of elements 113, 115, 117, and 118 are invited to suggest names.

Element 113 has a temporary working (systematic) name and symbol: ununtrium, Uut. It was discovered by the RIKEN collaboration team in Japan who fulfilled the criteria for element Z=113.

The media cover a story that scientists at the German Max Planck Institute produced a helium plasma contained for about a tenth of a second but at about 1000000 K. The next step at the Wendelstein 7-X (a stellarator fusion reactor) is to increase the stability of the plasma, to improve the heating method, and to increase the plasma temperature.

IUPAC have modified provisional recommendations for naming new elements as follows:

A procedure is proposed to name new chemical elements.  After the discovery of a new element is established by the joint IUPAC-IUPAP Working Group, the discoverers are invited to propose a name and a symbol to the IUPAC Inorganic Chemistry Division.  Elements can be named after a mythological concept, a mineral, a place or country, a property or a scientist.

There are many chemical web pages that display chemical structures within the web page itself. You, the viewer can then rotate the molecule on screen, read off bond lengths and angles, and do other useful things. To do this, a free piece of software known as a plug-in is required. There are at least two plugins available for you to use.

WebElements now has the capability for authors on the site to embed easily interactive spectra using the JSpecView applet via bbcode using jspecview tags. This is achieved by writing:[jspecview=600,400]pclanilIR.jdx[/jspecview].

The =600,400 bit gives the desired spectrum size while the file name to be displayed is included between the tags. The file is uploaded by authors who are assigned rights to upload attachments.
