You guys, the new elements are out! JAN 05 2016
IUPAC, the governing body for the official periodic table of elements, has announced the addition of four new elements to the table: ununtrium, ununpentium, ununseptium, and ununoctium. Those are working names...the teams that discovered each element has been invited to name them.
The proposed names and symbols will be checked by the Inorganic Chemistry Division of IUPAC for consistency, translatability into other languages, possible prior historic use for other cases, etc. New elements can be named after a mythological concept, a mineral, a place or country, a property or a scientist.
Ununoctium is so unstable that its half-life is 0.89 milliseconds and only three or four atoms of the substance have been produced in the past 10 years.
