nine
Fluorine's atomic number is 9. Thus, fluorine has 9 protons and 9 electrons. As with every atom, all 9 of fluorine's electrons are found in the electron cloud.
If the ion is the most common anion of fluorine, a fluoride ion, it contains 10 electrons.
The number of electrons is always the same as the atomic number. That gives you the number of protons and electrons. The atomic mass has nothing to do with it. What is the atomic number? That is your answer.
it has 7 valence electrons, which is the number of electrons on the outer energy level, so it needs 7.
Number of neutrons = Mass number - atomic number = 23 - 9 = 14
The total number of electrons in a neutral fluorine atom is 9, which is the atomic number of fluorine.
Fluorine has the atomic number of 9. This means it has 9 protons in the nuclei of its atoms. So, a neutral fluorine atom would also have 9 electrons.
No, fluorine has nine electrons total and seven valence electrons.
in a normal F- ion there are 10 electrons total (but 8 in the outer energy level)
An atom of fluorine has 9 electrons in total. Electrons are equal to protons when the atom isn't an ion, and the number of protons is also the atomic number of the element, so you just need to know the atomic number to find out the number of electrons or protons.
In a neutral atom of fluorine, there are 9 electrons. The number of neutrons varies with an isotope's mass number.
Fluorine has 9 in total. 7 in the outermost shell
There are 9 total electrons in an atom of Fluorine.
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 fluoride atom has 7 electrons in its outer shell (9 in total) but the ion of fluorine has any number of electrons in the outer shell. eg. F+ = the normal fluorine atom but with one less electron.
Since fluorine and chlorine are in family 7A, they each have 7 valence electrons. The number of the family corresponds to the number of valence electrons.
Fluorine's atomic number is 9. Thus, fluorine has 9 protons and 9 electrons. As with every atom, all 9 of fluorine's electrons are found in the electron cloud.
