one neutron
fluorine-18 is radioactive undergoing beta+ decay with a halflife of 1.87 hours
fluorine-19 is the only stable isotope of fluorine
being slightly lighter, fluorine-18 will participate slightly faster in chemical reactions than fluorine-19 will
etc.
Fluorine 19 has one neutron more than F18.
From looking at the chart of the nuclides, you can determine that Fluorine has a total of 13 isotopes (F-15 through F-27). Only one of Fluorine's isotopes is stable (F-19) and makes up 100% of the naturally occurring fluorine. The other 12 Fluorine isotopes are all radioactive and have half lives ranging from 5 x 10E-22 seconds (F-15) to 1.83 hours (F-18).
there are 19 protons in a fluorine-19 atom. Ironic huh? There are 9 protons in the fluorine 19 nucleus. There are 10 neutrons. The atomic number of fluorine is 9, which is the number of protons in a nucleus. The isotope number is the total number of protons and neutrons. The number of neutrons is different between fluorine 18 and 19 (9 and 10 respectively). They both have 9 protons.
Atoms of the same element that differ in the number of neutrons they contain are know as isotopes. Isotopes are identified by their mass number. For example hydrogen with an extra neutron is called Deuterium.
19F is the atomic symbol for fluorine-19.
Fluorine 19 has one neutron more than F18.
Almost all fluorine isotopes are Fluorine-19, which have 10 neutrons. Only trace amounts of Fluorine-18 can be found in nature.

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.
Fluorine is a non metal element. Mass number of it is 19.

The answer is Fluorine!Argon, one of the noble gases.
if u mean in the nucleus of fluorine then you can figure this out for yourself... its really simple considering that the electrons are the decimals so really all you have to do is subtract the atomic number (9) from the atomic mass (18) on the periodic table... so here it is: 18-9=9

The chemical symbol of fluorine is F. An isotope is written as 199F: 9 is the atomic number of F and 19 is atomic mass of the isotope. See the list of isotopes at the link below.
fluorine and neonAdded:To my best knowledge there are 3 naturally occurring isotopes with 10 neutrons: 8O(18) (0,2%),9F(19) (100%),10Ne(20) (91%),And additionally: only 12Mg(22) which is artificial and not stable (radio isotope).
19F is the atomic symbol for fluorine-19.
