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).
It's an average number allowing for the relative abundances of different isotopes.
In terms of atomic radius yes, nitrogen is larger than fluorine. However, the common fluorine isotopes have a greater mass than those of nitrogen.
Fluorine 19 has one neutron more than F18.
one neutronfluorine-18 is radioactive undergoing beta+ decay with a halflife of 1.87 hoursfluorine-19 is the only stable isotope of fluorinebeing slightly lighter, fluorine-18 will participate slightly faster in chemical reactions than fluorine-19 willetc.
Fluorine has 2 natural isotopes, 16 artificial isotopes and 1 artificial isomer.

No radioactive isotopes of fluorine are ordinarily found in nature. All elements have radioactive synthetic isotopes, however.

All isotopes and ions of fluorine have nine protons.
Almost all fluorine isotopes are Fluorine-19, which have 10 neutrons. Only trace amounts of Fluorine-18 can be found in nature.

In terms of atomic radius yes, nitrogen is larger than fluorine. However, the common fluorine isotopes have a greater mass than those of nitrogen.
Although there are 19 forms of fluorine, known as isotopes and an isomer, only one exists in significant quantities. It is 19F, meaning that it has an atomic mass of 19. The atomic number of fluorine is 9. Therefore, the number of neutrons in a nucleus of an atom of this isotope of fluorine is 10.
Fluorine-16 F-16 Use subscripts and superscripts with F to indicate mass and atomic number
Fluorine 19 has one neutron more than F18.
All isotopes of fluorine, whether they are stable or unstable, have atomic number 9.
