Ununpentium is the temporary name of a synthetic superheavy element in the periodic table that has the temporary symbol Uup and has the atomic number 115. It is an extremely radioactive element; its most stable known isotope, ununpentium-289, has a half-life of only 220 milliseconds. It is also known as eka-bismuth or simply element 115. Ununpentium was first created in 2003 by a team composed of Russian scientists at the Joint Institute for Nuclear Research (JINR) in Dubna, and American scientists at the Lawrence Livermore National Laboratory. In December 2015, it was recognized as a new element by the International Union of Pure and Applied Chemistry (IUPAC) and the International Union of Pure and Applied Physics (IUPAP). About 100 atoms of ununpentium have been observed to date, all of which have been shown to have mass numbers from 287 to 290.
In the periodic table, it is a p-block transactinide element. It is a member of the 7th period and is placed in group 15 as the heaviest pnictogen, although it has not been confirmed to behave as the heavier homologue to the pnictogen bismuth. Ununpentium is calculated to have some similar properties to its lighter homologues, nitrogen, phosphorus, arsenic, antimony, and bismuth, although it should also show several major differences from them.
Party Political Broadcast for the 2015 party conference #UUP15
Ladies and gentlemen, may I present to you the 115th element! Right now, you can call it Ununpentium, but soon it might be known as Ununpentium Part II The Wrath of Kahn. Scientists who were forcefully being optimistic tends to try hard working to slam between two elements 95 Am & 20 Ca = 115 Uup (Ununpentium) just to see if it really exist. But yes, hoping they should name it Plazartium because of Bob Lazar. In Pentium separates the P is in Pen & tium then squeeze in Lazar. That's P-Lazar-tium. We should honor Bob Lazar. But Bob & John Lear found out the Los Alamos facilities have that E-115. Either "Plazartium" or "UnunPlazartium" because the fact that there's a World true history first man discovery behind this element 115 so known obviously logical fact suggestions. Changing World H...

The Ulster Unionist Party's ruling body has voted unanimously in favour of withdrawing from government. It follows a proposal made by the UUP's leader Mike Nesbitt to the party's executive. He had made the recommendation after police in Northern Ireland said members of the Provisional IRA were involved in murdering ex-IRA man Kevin McGuigan Sr. Mr Nesbitt said Danny Kennedy, the UUP's only executive minister, would tender his resignation on Tuesday.
Researchers in Sweden say they've made a new element, calling it Ununpentium.
English/Nat The Northern Ireland peace process is again in tatters. The major Protestant party refused to nominate ministers for the new provincial administration and boycotted the assembly intended to inaugurate a new era of devolved government. The Ulster Unionists refusal to attend Thursday's session of Belfast's year-old legislature threw years of peacemaking efforts into disarray. Their unexpectedly stubborn stand dealt a severe blow to British Prime Minister Tony Blair's hopes of forming a power-sharing administration of Protestants and Catholics. And in an unexpected move, Seamus Mallon of the moderate S-D-L-P condemned the Ulster Unionists' tactics - and immediately resigned as the Cabinet's would-be deputy first minister. A major blow to the Northern Ireland ...
The poster on the wall of a dear friend
I wish there was a way that I could show you how your songs set me free
The hero of them all
You're a legend
I guess I'll never get a chance to know you
Still you're close as can be
Make the bandstand to a dreamland, Rubber Ball Man
Clapping your hands, let your feet dance, Rubber Ball Man
When you're jumping up and down, nobody's standing still
Some of us dreaming, some of us screaming
