Fluorine (F22) Molecule Lewis Structure

Fluorine is a diatomic molecule and contains only two fluorine atoms. Lewis structure of fluorine molecule contains only one F-F bond and each fluorine atom has three lone pairs in their last shells. It is very easy to draw the F2 molecule lewis structure.

F2 fluorine lewis structure

There is only one single bond between two fluorine atoms and three lone pairs on each fluorine atom. So, this lewis structure is a very simple and drawing it is a not a challenging task.



Steps of drawing lewis structure of F2 molecule

When we draw a lewis structure, guidelines are given. Number of steps can be changed according the complexity of the molecule or ion. Because F2 is a simple molecule, it is extremely easy to draw the lewis structure of it. However those all steps are mentioned and explained in detail in this tutorial for your knowledge.

  1. Find total number of electrons of the valance shells of fluorine atoms
  2. Total electrons pairs existing as lone pairs and bonds
  3. Center atom selection
  4. Mark lone pairs on atoms
  5. Mark charges on atoms if there are charges.
  6. Check the stability and minimize charges on atoms by converting lone pairs to bonds to obtain best lewis structure.

Total number of electrons of the valance shells of F2 molecule

There is only one element in fluorine molecule. Fluorine is a group VIIA element in the periodic table and contains seven electrons in its last shell. Now, we know how many electrons are there in valence shells of fluorine atoms.


  • valence electrons given by fluorine atoms = 7 * 2 = 14

  • Total valence electrons = 14

Total valence electrons pairs

Total valance electrons pairs = σ bonds + π bonds + lone pairs at valence shells

Total electron pairs are determined by dividing the number total valence electrons by two. For, F2 molecule, Total pairs of electrons are seven in their valence shells.



Center atom of F2 molecule

Because, there are only two atoms and both atoms belongs to same element, do not need to worry about center atom selection.

Lone pairs on atoms

After determining the center atom and sketch of F2 molecule, we can start to mark lone pairs on atoms. Remember that, there are total of seven electron pairs.

  • There is already one bond in the drawn skeletal. So, there are six remaining lone pairs to mark on fluorine atoms.
  • Because, there is no center atom, we can mark remaining lone pairs on both chlorine atoms. Each fluorine atom will take three lone pairs.
  • Now, all valence electrons pairs are marked.

Mark charges on atoms

There are no charges on fluorine atoms to mark in the above structure.



Check the stability and minimize charges on atoms by converting lone pairs to bonds

Because, there are no charges in above structure, do not need to follow this step to reduce charges to get the most stable structure. That means, we have already found the best lewis structure for fluorine molecule.
