[WD]Periodic Table Adds Three Elements.

Meet darmstadtium (Ds), roentgenium (Rg) and copernicium (Cn) -- three new super-heavy elements that are so large and unstable that they can only be synthetically produced in the lab and, even then, rapidly decay into lighter elements.

All three were first synthesised in the mid 1990s at the Gesellschaft für Schwerionenforschung (GSI) in Darmstadt, Germany -- Ds was made by bombarding a lead-208 target with nickel-62 ion, Rg by the cold fusion between nickel ions and a bismuth target, and Cn by firing accelerated zinc-70 nuclei at a target made of lead-208 nuclei
Good for everybody, except AP Chem students.

No one studies synthesised elements.

At least not me.

Technically. The periodic table can go on forever...


And if you think about it. So little is know about these elements that scientist are really just guessing what they can do.

So its might not even be bad to AP students. Since for the most part it wont really matter..

I'm curious what (if anything) these super unstable elements might be useful for? Or is this a purely scientific endeavor?
post #6 of 60
I don't get it, why find "new" elements, when they only appear for a fraction of time? Is it possible to make them more stable? Except freezing them to 0K

This is intriguing to me, I can only wonder what kind of things these elements can be used for if we accomplish stabilizing them and keeping them "alive." It also makes me think about all the other elements that can possibly be synthesized.

There was a period of @50 years where "we" couldn't harness Titanium from ilmenite because it was unstable yet...We knew it existed...Just saying.

Pure science is about discovering new stuff. It is not about practicality.
