What is the Atomic Mass of Fluorine?

Atomic Mass of Fluorine is                   .

A) 19

B)  18

C)  20

D)  17

Answer:

Option A) 19 is correct.

Explanation:

Atomic Mass of any substance is the sum of the number of protons and the number of neutrons in the nucleus of that atom.



For Fluorine,

  • Number of Protons =  9
  • Number of Neutrons =  10

Atomic Mass of Fluorine =  9 + 10 = 19



In absolute terms, the average atomic mass of Fluorine is 18.998403 amu. It is calculated taking into account all the isotopes of Fluorine.
