The distance between Hydrogen atoms in C₂H₂ = 121pm
An atom of the chemical element hydrogen is known as a hydrogen atom. The Coulomb force holds a single positively charged proton and a single negatively charged electron to the nucleus of the electrically neutral atom. About 75% of the universe's total baryonic mass is made up of atomic hydrogen.
Isolated hydrogen atoms, often known as "atomic hydrogen," are highly uncommon in normal life on Earth. In contrast, a hydrogen atom usually joins forces with other atoms to form compounds or with another hydrogen atom to generate common (diatomic) hydrogen gas, H2. In everyday English, the terms "atomic hydrogen" and "hydrogen atom" have similar but distinct meanings.
A water molecule, for instance, has two hydrogen atoms but no atomic hydrogen (which would refer to isolated hydrogen atoms)
