Does anyone know of a blog, website, news server, or listserv to which one may subscribe to be notified when these elements get their official names?
According to this press release from 8 June 2016, IUPAC proposes names for the four new elements as follows:
nihonium and symbol Nh, for the element 113,
moscovium and symbol Mc, for the element 115,
tennessine and symbol Ts, for the element 117, and
oganesson and symbol Og, for the element 118.
The public review (comments by 8 November 2016) of the provisional recommendations can be found here.
IUPAC will certainly have a press release on their news page, given that they are officially responsible for the names.
Currently, that's at this address: http://www.iupac.org/news/latest-news.html
Sadly, they don't appear to have an RSS feed. (Not even an Atom feed [rimshot noise].)
