Fluorine molecule · F2

F2 Lewis Structure

Each fluorine contributes seven valence electrons. One shared pair forms the F–F bond, while three lone pairs remain on each atom to complete both octets.

F2 overview

The single bond uses two electrons. The remaining twelve electrons become six lone pairs, divided equally between the two fluorine atoms.

How to draw F2

  1. Count 14 valence electrons.
  2. Draw one F–F single bond.
  3. Add three lone pairs to the first fluorine.
  4. Add three lone pairs to the second fluorine.
  5. Verify that both atoms have octets and formal charge zero.

Bonding interpretation

The atoms are identical, so the bond is nonpolar. A Lewis diagram records electron pairs but does not show bond length or molecular orbital details.

Common mistakes

  • Drawing a double bond.
  • Showing only one or two lone pairs per fluorine.
  • Using only eight total electrons.
  • Assigning charges to neutral F₂.
