Note: This model of covalent bonding for the hydrogen molecule (H2) starts with 2 individual hydrogen atoms. In reality, hydrogen atoms are never separate to start with. They are always bonded with ...

Scientists have measured the shortest interval of time ever recorded, clocking how long it takes a particle of light to cross a single molecule of hydrogen.

Scientists have measured the shortest unit of time ever, the time it takes for a particle of light to cross a hydrogen molecule.

Using a scanning tunneling microscope equipped with a femtosecond terahertz laser, scientists have exploited the quantum properties of a two-atom hydrogen molecule to observe changes in the ...
