Quick Answer: The Hydrogen Molecule Model represents molecular hydrogen, H2, as two hydrogen atoms joined by a single covalent H–H bond formed from a shared pair of electrons.
Last updated: October 2026
Key Features
Shows an H2 molecule made of two hydrogen atoms
Represents the single covalent bond as H–H
Each hydrogen atom has atomic number 1 and the configuration 1s¹
Helps students tell a single H atom apart from a diatomic H2 molecule

About This Product
Teachers point out the two hydrogen atoms, each with one electron in its 1s orbital, then use the model to show how those two electrons pair up in the bonding region between the nuclei. This explains covalent bonding through a shared electron pair before hydrogen is compared with other diatomic and molecular substances.
Frequently Asked Questions
Q1. What is the difference between a hydrogen atom and a hydrogen molecule? A hydrogen atom, H, has one proton and one electron. A hydrogen molecule, H2, is two such atoms held together by a shared pair of electrons in a single covalent bond.
