by WebElements: the periodic table on the web

This is for web authors.

Have a look at JSmol where you can find information about the JSMol molecule viewer. With this you can publish chemical structures in your web pages and it usually works just fine provided your viewers have fast access to the internet. For an example of JSmol in action try this VSEPR tutorial.

Quote: “JSmol is a JavaScript framework that allows web developers to create pages that utilize either Java or HTML5 (no Java), at will.

A paper accepted Aug 2013 and published in September 2013  entitled Spectroscopy of element 115 decay chains by D. Rudolph et al. provides additional evidence for element 115.1

Abstract

A high-resolution α X-ray and γ-ray coincidence spectroscopy experiment was conducted at the GSI Helmholtzzentrum für Schwerionenforschung. Thirty correlated α-decay chains were detected following the fusion-evaporation reaction 48Ca + 243Am.

Press release from RIKEN Nishina Center for Accelerator-Based Science

The most unambiguous data to date on the elusive 113th atomic element has been obtained by researchers at the RIKEN Nishina Center for Accelerator-based Science (RNC). A chain of six consecutive alpha decays, produced in experiments at the RIKEN Radioisotope Beam Factory (RIBF), conclusively identifies the element through connections to well-known daughter nuclides.

The International Union of Pure and Applied Chemistry (IUPAC) has recommended names for elements 114 and 116. Scientists from the Lawrence Livermore National Laboratory (LLNL) and at Dubna proposed the names as Flerovium for element 114 and Livermorium for element 116.

Flerovium (atomic symbol Fl) was chosen to honor Flerov Laboratory of Nuclear Reactions, where superheavy elements, including element 114, were synthesized.

Attached find a printable (pdf) QR-coded periodic table with links to online periodic table data. QR codes are 2-dimensional bar codes readable by, for instance, some apps on iPhones and others.

Print the attached pdf on a big a piece of paper as possible, otherwise your QR reader may pick up an element you didn’t intend.

A news reports from IUPAC confirms the discoveries of elements 114 and 116. Proposals for the names of the two elements will follow in due course.

Discovery of Elements with Atomic Number 114 and 116

Priority for the discovery of the elements with atomic number 114 and 116 has been assigned, in accordance with the agreed criteria, to collaborative work between scientists from the Joint Institute for Nuclear Research in Dubna, Russia and from Lawrence Livermore, California, USA (the Dubna-Livermore collaborations).

The BBC is airing some “periodic tales” on Radio 4. Familiar Radio 4 voices introduce elements from the Periodic Table and the unique roles they play in human existence – with a little help from the irreverent Tom Lehrer. Listen to these ten elements:

  • Krypton: Heidli Nicklaus on the Superman element, krypton
  • Helium: Brian Perkins dramatises the effects of Helium
  • Silver: Trevor Harrison (Eddie Grundy in the Archers) finds some unusual properties of Silver
  • Cobalt: Hedli Nicklaus (Cathy Perks) takes on the goblin element of cobalt
  • Selenium: Carole Boyd (The Archers’ Linda Snell) unearths selenium
  • Oxygen: Brian Perkins bravely dramatises the effects of oxygen
  • Arsenic: Charlotte Green takes on the deadly history of arsenic
  • Mercury: Carole Boyd (Linda Snell) reflects on mercury, the poisonous liquid metal
  • Iodine: Charlotte Green on the discovery of iodine’s essential place in brain development
  • Nickel: Trevor Harrison reveals that the space station Mir is largely made of nickel

[Note added Dec 2009: sadly these recordings no longer exist on the BBC site.
