Answer:
10 neutrons
Explanation:
The mass of is made up of the total protons and neutrons in an atom.
Each particle has a mass of 1 amu (atomic mass unit).
All fluorine atoms have 9 protons.
If each proton is 1 amu, the protons must contribute 9 amu to the total mass of the atom (9 x 1 amu = 9 amu).
This means the neutrons must contribute a total mass of 10 amu (18.998 amu - 9 amu = ~10 amu).
If each neutron has a mass of 1 amu, there must be 10 neutrons in a fluorine atom (10 amu / 1 amu = 10 amu).
