Both fluorine and chlorine have seven valence electrons. In the case of fluorine they're in n=2 and in the case of fluorine they're in n=3, but other than that they're the same.
Fluorine has 7 valence electrons. 2 In the first electron shell, and 5 in the second electron shell.
Chlorine , fluorine ,and bromine belongs to halogen family. They have 7 valence electrons and gains 1 electron to form anions.
Any element in the halogen group will have seven valence electrons. These elements include fluorine, chlorine, bromine, iodine, and astatine.
Sodium can lose its one valence electron to form noble gas configuration. Chlorine will accept one electron to form noble gas configuration. Hence a ionic bond will e formed between sodium and chlorine.
The element chlorine has seven electrons in its valence shell.
Fluorine, chlorine bromine and iodine have seven electrons in their valence shells, and they all need one electron to have stabilized electron configuration. Therefore they are grouped in Group 17 (halogen group) of periodic table.
Fluorine has 7 valence electrons. 2 In the first electron shell, and 5 in the second electron shell.
Chlorine , fluorine ,and bromine belongs to halogen family. They have 7 valence electrons and gains 1 electron to form anions.
Fluorine's atomic number is 9. Thus, neutral fluorine has 9 protons and 9 electrons. It's total configuration then is 1s2 2s2 2p5, so its valence configuration is 2s2 2p5.

Any element in the halogen group will have seven valence electrons. These elements include fluorine, chlorine, bromine, iodine, and astatine.
With an e- configuration of [Ne] 3s23p5, the atom will be found in Group VII A, meaning that there are 7 valence electrons.
Fluorine has 7 valence electrons and should gain 1 more electron.
this is because a fluorine ion is one electron short of a full valence shell,which makes getting another electron to fill the shell very favourable,filling the shell makes the molecule much more stable
[He] 2s2 3p5 is the electronic configuration of a neutral Fluorine atom. It's -1 ion (F-, fluoride ion), however is: [He] 2s2 3p6, or [Ne].
There are 7 valence electrons in chlorine.
