Dubnium is an artificial chemical element and hasn't stable isotopes.
Number of neutrons = Atomic mass of an isotope - Atomic number of the element The atomic number of dubnium is 105; dubnium has many isotopes and of course each idotope has a different number of neutrons - dubnium has now 13 isotopes and 1 isomer.
The decay products of bohrium isotopes are dubnium isotopes.
copper has 2 stable isotopes
No, there are many stable isotopes.
It has 10
it has 3 stable isotopes
No, most isotopes are not stable. Many isotopes are radioactive and decay over time, releasing radiation in the process. Only a few isotopes are stable and do not undergo radioactive decay.
Db stands for Dubnium, which is a synthetic element in the periodic table with the atomic number 105. It is named after the town of Dubna in Russia, where it was discovered. Dubnium is a member of the transactinide series and is classified as a d-block element. It is highly radioactive and has no stable isotopes.
There is one stable isotope in Niobium, Nb93 there are 28 known isotopes in all.
Oxygen consists of three stable isotopes: 16O, 17O, and 18O
Dubnium's mass number is about 262, because it is the atomic mass of the closest stable isotope.
