Physicists have clocked the shortest time span ever
The experiment revealed how long it takes light to cross a hydrogen molecule: just a couple hundred zeptoseconds.
- Chemistry
Scientists Say: Molecule
A molecule is a group of atoms linked with chemical bonds. It’s the smallest particle of a substance that has all of its chemical properties.
