Dubnium is an artificial element and was first created and thus found in a laboratory in the city of Dubna.
Dubnium was discovered in 1968 by a team from Dubna, Russia:
Gheorghi Nikolaevici Flerov, V.A. Druin, A.G. Demin, Iu.V. Lobanov, Nikolai Constantinovici 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
A strange and long history of the name: nielsbohrium, hahnium, unnilpentium, joliotium and finally, after 1997 - dubnium (the official name of IUPAC).

Berkelium is only an artificial element.
Nitrogen.
Dubnium is an artificial chemical element.
As all other chemical elements dubnium contain protons, neutrons and electrons.
Dubnium
The most stable (not abundant) isotope of dubnium is 268Db.
The element dubnium is not mined. This metal is what is called a transactinide element, and it is not found anywhere in nature. All of the dubnium on earth has been synthesized in high energy physics laboratories. Additionally, all of it is unstable, and it is, therefore, radioactive.

Yes, dubnium is a rare and man-made element. It is part of the transuranium series and is produced artificially in nuclear reactors. It has a short half-life and is not found in nature in significant quantities.
Dubnium is a rare and highly radioactive element that is not found in nature and has no practical use outside of scientific research. As a result, it does not have a specific monetary value.
Dubnium has 105 protons.
Dubnium has 105 electrons.
Dubnium was obtained only in quantities of some atoms !
