copper has 2 stable isotopes
No, there are many stable isotopes.
It has 10
Dubnium is an artificial chemical element and hasn't stable isotopes.
it has 3 stable isotopes
Fluorine has 2 natural isotopes, 16 artificial isotopes and 1 artificial isomer.
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.
From looking at the chart of the nuclides, you can determine that Fluorine has a total of 13 isotopes (F-15 through F-27). Only one of Fluorine's isotopes is stable (F-19) and makes up 100% of the naturally occurring fluorine. The other 12 Fluorine isotopes are all radioactive and have half lives ranging from 5 x 10E-22 seconds (F-15) to 1.83 hours (F-18).
All isotopes and ions of fluorine have nine protons.
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
Fluorine is a stable element.yes.
