Fluorine |

do you think that fluorine has common isotopes?
if so justify your answer.

Answer 1

Two isotopes: 18F and 19F.
Although fluorine has multiple isotopes, only one of these isotopes (19F) is stable, and the others have short half-lives and are not found in nature. Fluorine is thus a mononuclidic element.
