There are 9 protons and 9 electrons in a fluorine atom The only stable isotope has 10 neutrons
there are 19 protons in a fluorine-19 atom. Ironic huh? There are 9 protons in the fluorine 19 nucleus. There are 10 neutrons. The atomic number of fluorine is 9, which is the number of protons in a nucleus. The isotope number is the total number of protons and neutrons. The number of neutrons is different between fluorine 18 and 19 (9 and 10 respectively). They both have 9 protons.
Answer is in the question itself. 19. Because atomic mass is nearly equal to the mass number of the atom. Mass number is always a round number that is natural number. The proton code for fluorine atom is 9. Mass number is the total number of protons and neutrons. So for mass number 19, the number of neutrons will be 19 - 9 = 10.
It would depend on the isotope.

The stable isotope, Fluorine-19, has 10 neutrons.
In a fluorine atom: 9 protons, 10 neutrons, and 9 electrons.
subtract the atomic number by the Atomic Mass, and that is the answer. if its a neutral atom, there are probably the same number neutrons as protons.

The atomic number of fluorine is 9. So there are 9 protons and 9 electrons. The number of neutrons depends on the isotope. F-19 isotope has 10 neutrons.
Virtually 100% of fluorine atoms have 10 neutrons. (Wikipedia)
An atom of Fluorine has the atomic number 9 and the mass number 19 (rounded up). This means it has 9 electrons, 9 protons and (19-9) 10 neutrons. The proton and electron count are taken from the atomic number. The mass number - the atomic number gives the number of neutrons.
In Fluorine - 19 there are 10 neutrons
How many neutrons would it have if it had 11 neutrons? 11.
