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.
