2 new elments discovered in 2004 ?

Not really: Uut = Ununtrium, element 113
284113Uut --> 279111Uuu + 42He (1196 milliseconds)

1196 milliseconds! which is 1.196 seconds.

at least their half-lives are higher than that of muons:
2.2 microseconds

wait... its measured in microseconds.... so it would be
2.2 * 10^ -3 milliseconds
from
http://en.wikipedia.org/wiki/Muon

charged pions' are even worse!
2.6 × 10−5 milliseconds
from http://en.wikipedia.org/wiki/Pion

Wow! More than a second! But still, where are the commercial properties? It is far too short lived to be used in chemistry. Too short lived to be used as a nuclear fuel.

The only real benefit is to increase our understanding of how atoms are put together, but we already have good knowledge of many, and it still hasn't helped much.

I am going to be a heretic here (but then ain't I always?). I think particle physics has got just about all the useful data it is going to get. What we need is not more exotic atoms, or higher energy particles, but somebody bright enough to put all the clues together and come up with a solution.

There are computers powerful enough to deduce the properties of particles and atoms IF they were programed with a complete and accurate description of the fundamental forces involved.

Something binds protons and neutrons together to form atoms. I see no reason why that binding force should be any more complicated, in terms of its fundamental nature, than gravity or electromagnetism. It is just complex in operation.

yeah, there is no commerical purpose... the amount of element produced is so limited.

anyway, it will be cool to see a new period on the periodic table...

in period 8th, the electrons might fill the sublevel s, then.... will period 8 have p sublevel? or is the electron gonna fill the f, d or....hmmm, the answer will come once the scientists hit period 8

Muons are create from upper atmosphere by cosmic rays. If it wern't for time dilation they
would get farther than 684 or feet ! Can this be comercially harnessed. If I knew, I'd be
doing it. If you don't consider, then nothing will get discovered.

You seem to have out of date info or your looking at the glass half empty. I just read how
they are creating these new round discoveries. The scientist are speaking about an island
around 130. Of course I must admit that many years earlier when 105 was found, it was
thought that the island would be around 118. Still have to look, don't we ?

I noticed those names on the website. Can't they come up with better temporary naming
convention ?

it has to go through the IUPAC first.
website: http://www.iupac.org/index_to.html
I agree, these names are in fact weird... hard to memorize. They should just assign them like A, B, C, Aa, Ab, Ac... but the problem is that some european countries might not want em in english.

We talked about this in our science class in September of 2004 a manmade element created by Japanese scientist was created. They tried to create this element by using a cyclotron to attack the atoms of bismuth, number 83 with the atoms of zinc numbered 30. By using the cyclotron they were successful in creating the new element after 80 days of attacking and the new element disintegrated in 0.3 of a millisecond. This new element whose atomic number is 113 is the heaviest known element and may possibly be named “japonium.” It has a mass number of 278 with 113 protons and 165 neutrons in its nucleus.
