Why is the mass number of fluorine-19?
Fluorine (9F) has 18 known isotopes ranging from 13F to 31F (with the exception of 30F) and two isomers (18mF and 26mF). Only fluorine-19 is stable and naturally occurring; therefore, fluorine is a monoisotopic and mononuclidic element, and only artificially produced fluorine isotopes have mass numbers other than 19.

What has 9 protons and a mass number of 19?
Fluorine
By looking at the periodic table, you will see that Fluorine has 9 protons. Since the number of electrons equal the number of protons, Fluorine has 9 electrons as well. Meanwhile, it’s mass number of 19, minus 10 neutrons, gives you 9 protons or electrons. Hence, the atom would be Fluorine.
What is the charge for fluorine 19?
It has an extra electron, and so it has a negative charge.
How many neutrons are in 10 grams fluorine 19?
This isotope of fluorine has 9 protons, 9 electrons and 10 neutrons.
What element has the mass number of 19 and 9 electrons?
Fluorine is the element in question, as its atomic number is 9 . You would name this particular isotope using the mass number. It would be called fluorine-19.
