Lewis Structure of H₂ (Hydrogen)
What is the Lewis structure of H₂?
H₂ has 2 valence electrons, 1 bonding electron pair. H₂ is the simplest Lewis structure. Each hydrogen contributes 1 valence electron (2 total). The two electrons form a single covalent bond, giving each H a filled 1s shell (duet rule).

Step 1: Count Valence Electrons
Hydrogen is in Group 1A, so each H has 1 valence electron. Two H atoms contribute 2 total valence electrons.
Step 2: Draw the Skeleton
The two H atoms are connected by a single bond, using both valence electrons.
Step 3: Distribute Lone Pairs
There are no remaining electrons, so no lone pairs are needed.
Step 5: Check Formal Charges
- H: FC = 1 - 0 - ½(2) = 0
