1.	the atomic number of fluorine is 9 and its atomic masses 19 what is the number of neutrons present in the nucleus
Answer» Atomic NUMBER of FLUORINE = 9 Atomic mass of Fluorine = 19 We know that the number of neutrons in atomic mass is the remaining particles LEFT after excluding the protons in it. Hence, Number of neutrons in an atom of Fluorine = Atomic Mass - Atomic Number Number of neutrons in an atom of Fluorine = 19 - 9 = 10
