The Lewis dot structure for H₂ (hydrogen gas) represents the covalent bond between two hydrogen atoms, each sharing one electron to form a stable diatomic molecule.
Representation:
- Each hydrogen atom has one valence electron.
- In the Lewis structure, the two electrons are shared to form a single covalent bond between the hydrogen atoms.
- The structure is written as H:H or H—H, where the colon or line indicates the shared pair of electrons (bond).
Explanation:
Hydrogen achieves a stable configuration by sharing its single electron with another hydrogen atom, fulfilling the duet rule (a full outer shell with 2 electrons). This bond results in a stable diatomic molecule, which is the most common form of hydrogen in nature.
