A neutral atom of fluorine has the following:

  • Protons: The atomic number of fluorine is 9, which means it has 9 protons.
  • Electrons: In a neutral atom, the number of electrons equals the number of protons, so fluorine also has 9 electrons.
  • Neutrons: The atomic mass of fluorine is approximately 19. To find the number of neutrons, you subtract the number of protons from the atomic mass: 19 (atomic mass) - 9 (protons) = 10 neutrons.

Putting this all together, a neutral atom of fluorine has:

  • 9 electrons
  • 9 protons
  • 10 neutrons

Thus, the correct response is: 9 electrons, 9 protons, 10 neutrons.
