Dubnium was discovered in 1968 by a team from Dubna, Russia:
Gheorghi Nikolaevici Flerov, V.A. Druin, A.G. Demin, Iu.V. Lobanov, Nikolai Cons-tantinovici Skobelev, G.N. Akapiev, B.V. Fefilov, I.V. Kolesov, K.A. Gavrilov, Iu.P. Haritonov, L.P. Şelnokov .
The nuclear reaction used was:
24395Am + 2210Ne → 260105Db + 5 n
Dubnium is not flammable.
The name dubnium is derived from the name of the Russian town Dubna (where is the Joint Institute for Nuclear Research (JINR)).
Oh, dude, dubnium is a super rare element that's not really sold on eBay last time I checked. It's not like you can just pop down to the store and pick some up. But, like, if you're really curious, the cost of producing dubnium in a lab is crazy expensive, probably more than your monthly rent.
These properties are not determined today.
When did he discovered? Do you mean what? He discovered Yellow Fever was transmitted by mosquitoes. And if you mean when did he discover it, then the answer you are looking for is he led a research team that discovered this in 1900.
