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).
Fluorine is in Period 2. Its atomic number is 9.
9 electrons in a neutral atom.
Fluorine is in period 2
period of fluorine is 2
group - 17 and period - 2nd
17
The fluorine-19 isotope.
Number of neutrons = Mass number - atomic number = 23 - 9 = 14
The nine protons tells you that the atomic number of the element is going to be nine. Element #9 happens to be Fluorine (F). The most common isotope of fluorine has t10 neutrons. If it doesn't have nine protons, though, it isn't fluorine.
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.
The chemical notation is 19F.
The fluorine isotope differs from the fluorine ion because the fluorine isotope has a different number of neutrons from normal, while the ion has a different number of electrons. An isotope will have the same number of electrons as its atomic number (the number of protons), while the ion will add (more common in the case of fluorine) or subtract (very rare in the case of fluorine) electrons to the atom. The only thing they are similar in is the number of protons they have, which are the same.
The atomic number for any isotope of fluorine is always 9; that is the "definition" of fluorine.
In a neutral atom of fluorine, there are 9 electrons. The number of neutrons varies with an isotope's mass number.
The only stable isotope has 10 neutrons
Fluorine (F), the isotope 19F.
The fluorine-19 isotope.
The atomic number of fluorine is 9. So there are 9 protons and 9 electrons. The number of neutrons depends on the isotope. F-19 isotope has 10 neutrons.
Almost all fluorine isotopes are Fluorine-19, which have 10 neutrons. Only trace amounts of Fluorine-18 can be found in nature.
9
The number of protons is the same as the atomic number, which is nine in this case. If the atom is neutral, then the number of electrons will balance the number of protons, also nine in this case. Usually, the number of neutrons will vary with the isotope (atoms with a different number of neutrons) however, fluorine has only one natural isotope, 18F, with nine neutrons.See link below for more information on fluorine, as well as the related question below that will show you how to find the number of each subatomic particle in any atom.
The chemical symbol for fluorine isotope with 9 neutrons is 18F (18 is a superscript).
Number of neutrons = Mass number - atomic number = 23 - 9 = 14
