The Elements – Joe's Classes

Ununoctium

Ununoctium has the highest atomic number and highest atomic mass of all the elements discovered so far. Due to its high mass, it is very unstable. Only three or possibly four atoms of it have been detected since it was first synthesized in 2005.

Ununseptium

As of 2015, only fifteen atoms of this element have been observed, six in 2010, seven in 2012, and two in 2014. It may be located in the “island of stability”, a concept in which some superheavy elements may be more stable than would otherwise be expected.

Livermorium

Livermorium is an extremely radioactive superheavy synthetic element. It is named for the Lawrence Livermore National Laboratory in the US, which collaborated with the JINR in Dubna, Russia to discover it in 2000. The name was adopted on May 30, 2012.

Ununpentium

This element is extremely radioactive. Its most stable known isotope, 289Uup, has a half-life of 220 milliseconds. It was first created in 2003 by a team at JINR in Dubna, Russia, but it is still awaiting confirmation by IUPAC. About 50 atoms of it have been observed as of 2015.

Flerovium

Flerovium is an extremely radioactive superheavy synthetic element. Initial studies made in 2007–2008 indicated that it is unexpectedly volatile and may even be gaseous at standard temperature and pressure. Only about 80 atoms of it have been observed as of 2015.

Copernicium

Copernicium was first created in 1996 by the GSI Helmholtz Centre for Heavy Ion Research. In May 2009 the JWP officially recognized the GSI team as the discoverers of element 112. It is named after Polish astronomer Nicolaus Copernicus.

Roentgenium

Roentgenium was named for Wilhelm Conrad Röntgen, the discoverer of X-rays. It was first synthesized at GSI in Darmstadt, Germany in 1994. The team detected a single atom of the isotope 272Rg. They repeated this process in 2002 and produced 3 more atoms.

Darmstadtium

Darmstadtium was first created on November 9, 1994, at the Institute for Heavy Ion Research in Darmstadt, Germany. The team bombarded a 208Pb target with accelerated nuclei of 62Ni and detected a single atom of 269Ds. 9 atoms of 271Ds were also synthesized.

Meitnerium

The name meitnerium was suggested in honor of the Austrian physicist Lise Meitner, one of the discoverers of nuclear fission. It is the only element named for a (non mythological) woman. Of elements 104-109, it is the only one whose name was not disputed.
