two that are known
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.
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.
Fluorine has an atomic number of 9 and a relative atomic mass of 18.998 403 2(5). This means that it has 9 protons (atomic number). 18.998 403 2(5) is very close to 19 which means that most fluorine atoms have 19 protons and neutrons (added together). Since we already know there are 9 protons there must be 10 neutrons in most fluorine atoms (19-9=10).
Fluorine 19 has one neutron more than F18.
Fluorine has 2 natural isotopes, 16 artificial isotopes and 1 artificial isomer.

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

This means that it has 9 protons (atomic number). 18.998 403 2(5) is very close to 19 which means that most fluorine atoms have 19 protons and neutrons (added together). Since we already know there are 9 protons there must be 10 neutrons in most fluorine atoms (19-9=10).
The sum of elements like fluorine can be found by adding the atomic masses of its isotopes, weighted by their abundance in nature. The most abundant isotope of fluorine is fluorine-19, which has an atomic mass of 18.998403163 u. By accounting for the abundance of this isotope in nature, the average atomic mass of fluorine can be calculated, which is approximately 18.998 u.
