Based on the information above, do you think that fluorine has common isotopes? Justify your answer.
Answered by maham237 @
Answer is: fluorine does not have common isotopes, because its average atomic mass is 19.
Fluorine has only one isotope occurs naturally in abundance, the stable isotope F-19.
This isotope has:
1) n(p⁺) = 9; fluorine has atomic number Z = 9 (total number of protons).
2) n(e⁻) = 9; in an element, number of electrons and protons are the same.
3) n(n°) = 10; mass number of this isotope is A = 19. Mass nummber is total number of protons and neutrons in a nucleus, so number of neutrons is:
n(n°) = A-Z.
n(n°) = 19-9.
n(n°) =10.
