The WebElementsTM website just added elements 113 and 115 to the periodic table - closing the gaps that have been there since 114 and 116 got added a few years ago.

Livermore Scientists Team With Russia To Discover Elements 113 And 115

LIVERMORE, Calif. -- Scientists from the Glenn T. Seaborg Institute and the Chemical Biology and Nuclear Science Division at the Lawrence Livermore National Laboratory, in collaboration with researchers from the Joint Institute for Nuclear Research in Russia (JINR), have discovered the two newest super heavy elements, element 113 and element 115.

They've recently assigned a name and symbol to element number 111.
See http://www.webelements.com/ for more info.

# Name: roentgenium
# Symbol: Rg
# Atomic number: 111

Re "who comes up with these names no one can pronounce anyway"
Yeah, why can't those German scientists have plain English names?

Well, a Dr. Roentgen invented X-rays. I wonder if this element is radioactive, or if it's named after someone else.

Re "I wonder if this element is radioactive,"
Don't really have to wonder about that, just read the section for that element on http://www.webelements.com/ (click on 111 in its place on the chart). They made only a few atoms of the stuff, using a particle accelerator, and could identify it only by the decay products that appeared in seconds or less after that. (As a general rule, anything above 92 on the table is radioactive, and the higher the number, the more radioactive it is.)

Sorry, I didn't follow the link you posted in the other note. I read it at work and I never click on any posted links.

It's a list of all the elements known to man. (supposedly)
All chemicals, metals, etc... have been assigned a number and is in the periodic table.
Now if someone has a better explination, Please feel free to post it.

It's elementary.

It's the relationship between parallel universes, time relationships, a tear in the fabric of time and Quantum Quarks.
