How many valence electrons does fluorine have?
Fluorine has 7 .
Valence electrons are those electrons which are present in the outermost shell of an atom.
Fluorine has atomic number 9. Atomic number is the number of protons present in the nucleus of an atom.
In every stable (Neutral) atom the number of electrons are equal to the number of protons.
Therefore, the number of electrons in an atom of fluorine are 9.
The electronic configuration of fluorine is:
E.C:- k - 2 , L-7
The last shell of fluorine has 7 electrons. Therefore there are 7 valence electrons in an atom of fluorine.
