A neutral atom of fluorine has the same number of protons and electrons. Since fluorine has an atomic number of 9, it has 9 protons and 9 electrons.
To find the number of neutrons, you subtract the atomic number from the atomic mass. The atomic mass of fluorine is approximately 19, so:
Number of neutrons = Atomic mass - Atomic number = 19 - 9 = 10
Therefore, a neutral atom of fluorine has:
- 9 electrons
- 9 protons
- 10 neutrons
The correct answer is: 9 electrons, 9 protons, 10 neutrons.
