How do you draw the Lewis structure of HF?

HF has 8 valence electrons. H and F are connected by a single bond, using 2 of the 8 electrons. 6 electrons remain. They are placed as 3 lone pairs on fluorine to complete its octet.

What is the Lewis structure of HF?

HF has 8 valence electrons, 1 bonding electron pair, and 3 lone pairs. HF has 8 valence electrons. Two are shared in the H–F bond, and the remaining 6 are distributed as 3 lone pairs on fluorine, satisfying the octet rule for F and the duet rule for H.

Lewis structure of HF (Hydrogen Fluoride)

Formula	HF
Name	Hydrogen Fluoride
Total Valence Electrons	8
Lone Pairs	3
Has Resonance	No
Concept	Lone Pairs
Difficulty	Beginner

Step 1: Count Valence Electrons

H contributes 1 and F (Group 7A) contributes 7 valence electrons: 1 + 7 = 8 total.

Step 2: Draw the Skeleton

H and F are connected by a single bond, using 2 of the 8 electrons.

Step 3: Distribute Lone Pairs

6 electrons remain. They are placed as 3 lone pairs on fluorine to complete its octet.

Step 5: Check Formal Charges

H: FC = 1 - 0 - ½(2) = 0
F: FC = 7 - 6 - ½(2) = 0
