Fluorine has 2 natural isotopes, 16 artificial isotopes and 1 artificial isomer.
Yes, fluorine is highly reactive due to its strong electronegativity and small atomic size. It readily forms compounds with other elements, including metals, and can react explosively with certain substances.
two that are known
one
All the actinides isotopes are radioactive; and the majority are artificial isotopes.
You add or remove one or more neutrons from each atom.
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).
The atomic mass of fluorine is not exactly 19.000 because it is an average of all the isotopes of fluorine found in nature, taking into account their relative abundance. Fluorine has multiple isotopes with slightly different masses, which results in the average atomic mass being around 18.998.
All isotopes and ions of fluorine have nine protons.
Dubnium is an artificial chemical element and hasn't stable isotopes.
Neon isotopes can be used in dating meteoric rock and to investigate the creation of some isotopes in space.
Uranium has 3 natural isotopes (234, 235, 238) and 26 artificial isotopes.All the isotopes of uranium are radioactive.
Fluorine has 9 protons and 9 electrons. The number of neutrons can vary, as there are different isotopes of fluorine, but the most common isotope, fluorine-19, has 10 neutrons.
