by WebElements: the periodic table on the web

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.

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.”

I have restructured WebElements. The restructuring is all style at the front-end and reorganisation at the back-end, meaning all the errors in data are still there but they are displayed more beautifully and efficiently. Fixing some of those errors is now a priority.

All this should allow me to update content far more easily than has been the case, meaning things should move quicker.

Single-bonded cubic form of nitrogen

Everyone knows that elemental nitrogen exists in the atmosphere as dinitrogen, N2. There is a triple bond between the two nitrogen atoms. This is true – but under certain conditions, a fascinating N-N single bonded phase has been characterised.1

In 1985 it was predicted that at high pressure, nitrogen would transform to a solid with a single-bonded crystalline structure called polymeric nitrogen.
