New Elements: Uut and Uup
March 29, 2004 11:12 AM   Subscribe

Time to replace your old Periodic Table. ...a joint American-Russian team has found two new elements—numbers 113 and 115 on the periodic table—hinting at an impending breakthrough in creating novel forms of matter that will test our understanding of atomic behavior.

More about Ununtrium and Ununpentium (temporary names given to elements 113 and 115).

Who can tell me the atomic weight of bolognium?

This discovery confirms a long-held theory in nuclear physics that there is a region of enhanced stability at the margin of the periodic table.

Interesting. I didn't retain a lot of my high-school chemistry, but I remember a lot of internal eye-rolling when learning about elements whose lifespan was almost immeasurable. I did think this part was pretty amusing:

After running cyclotron day and night for a month, Patin and company produced four atoms each of the new elements, enough to study how they decay.

Well, I guess ROI is all a matter (pardon the pun) of perspective ;)

Cool link!

Uh... snacktacular?

A nice chart of atomic stability regions.

In SI units, it's delicious.

Smoke Detectors and Americium
Present at Creation (a little more on element 114)

That link rocks, vacapinta!

Or you could just replace your old periodic table with the much more compact periodic table of sloth.

A nice chart of atomic stability regions.

for some reason, that chart reminds me of the NES classic, Metroid?

Coo, vacapinta! Edward Tufte would be proud.

i love the science threads. like the life on mars and this one. seriously. i just always get to them too late.

I guess it's 118 that would be noble, which is what I'm really waiting for with eagerness.

Er, "cool," not "coo." Damn.

Glenn Seaborg announced the discovery of americium on a children's game show. Oh, how our intellectual culture has declined!
