All the information is there.
The 9 is the atomic number of the atom, an element by definition has only 1 possible atomic number. This means it has 9 protons in the nucleus, and if it is atomic (not ionic), as it is in this case, then it has 9 electrons as well.
19 refers to the Atomic Mass, this is the number of protons + the number of neutrons. So if we take the number of protons (9) away from the mass of the nucleus (19) we are left with 10, which must be the number of neutrons in this isotope of the element.
To recap
9 protons
9 electrons
10 neutrons

How many neutrons protons and electrons does fluorine have?
The atomic number of fluorine is 9. Atomic number = amount of protons, as well as the amount of electrons in an uncharged atom. Neutrons is simply atomic mass - atomic number, so 19 - 9. (all information found on periodic table). So, 9 protons, 9 electrons, 10 neutrons.
What is the number of protons in 19F -1?
Not sure what 19F -1 stands for but fluorine has 9 protons.
What is the shorthand notation for fluorine 19?
19F.
How many nuetrons does fluorine contain?
Although there are 19 forms of fluorine, known as isotopes and an isomer, only one exists in significant quantities. It is 19F, meaning that it has an atomic mass of 19. The atomic number of fluorine is 9. Therefore, the number of neutrons in a nucleus of an atom of this isotope of fluorine is 10.
How can you find the number of protons and electrons and neutrons in an atom or ion?
The number of protons in an atom is its atomic number, which can be found on the periodic table. The number of electrons is equal to the number of protons in a neutral atom. To find the number of neutrons, subtract the atomic number from the atomic mass of the atom. For ions, the number of protons remains the same as the atomic number, but the number of electrons changes based on the charge of the ion.
How many neutrons protons and electrons does fluorine have?
The atomic number of fluorine is 9. Atomic number = amount of protons, as well as the amount of electrons in an uncharged atom. Neutrons is simply atomic mass - atomic number, so 19 - 9. (all information found on periodic table). So, 9 protons, 9 electrons, 10 neutrons.
