Sasha was developing an atomic model for Fluorine. How many neutrons should Jenny include in the nucleus of her model and why?

• She should include 10 neutrons, because number of neutrons is equal to double the atomic number

• She should include 9 neutrons, because fluorine has an stomic mass of 10 and the number of neutrons is always equal to the atomic mass

• She should include 10 neutrons, becuase the number of neutrons is equal to the atomic mass minus the atomic number
