The typical size of atoms and small molecules is around 1 × 10-10 m (0.1 nm). For example: diameter of a hydrogen atom, H 1.0 × 10-10 m width of a hydrogen molecule, H 2 2.9 × 10-10 m ...

Two experiment collaborations, the g2p and EG4 collaborations, combined their complementary data on the proton's inner ...

Hydrogen and carbon monoxide travel at different speeds due to their molecular size relative to the size of nanoscale tunnels in the structure. While hydrogen binds reversibly, carbon monoxide ...
