Lewis Structure of F₂ (Fluorine)
What is the Lewis structure of F₂?
F₂ has 14 valence electrons, 1 bonding electron pair, and 6 lone pairs. F₂ has 14 valence electrons. Two are shared in the F-F single bond, and each fluorine has 3 lone pairs (6 electrons). Both atoms satisfy the octet rule with formal charges of zero.
| Formula | F₂ |
| Name | Fluorine |
| Total Valence Electrons | 14 |
| Lone Pairs | 6 |
| Has Resonance | No |
| Concept | Lone Pairs |
| Difficulty | Beginner |
Step 1: Count Valence Electrons
Each F (Group 7A) has 7 valence electrons: 7 + 7 = 14 total.
Step 2: Draw the Skeleton
The two F atoms share a single bond, using 2 electrons. 12 remain.
Step 3: Distribute Lone Pairs
Each F gets 3 lone pairs (6 electrons each), using all 12 remaining electrons and completing both octets.
Step 5: Check Formal Charges
- F: FC = 7 - 6 - ½(2) = 0
