by WebElements: the periodic table on the web

Have periodic table towel will travel. That’s Mount Vesuvius in the background. Lots of chemistry in a volcano.

I rather like H where I put it (above F) in the table but you may not!

International Union of Pure and Applied Chemistry (IUPAC) have confirmed the names of elements 113, 115, 117, and 118 as:

  • Nihonium and symbol Nh, for element 113
  • Moscovium and symbol Mc, for element 115
  • Tennessine and symbol Ts, for element 117
  • Oganesson and symbol Og, for element 118

This followed a 5-month period of public review after which the names earlier proposed by the discoverers were approved by IUPAC.

Wondering why the most expensive diamond ever (the Oppenheimer Blue, £35 million) is blue – it is because of boron impurities, element 5 in the periodic table.

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.

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.
