How long does it take an electron to travel from an atom to the next atom?

Scientists say they have discovered how long it takes electrons to hop between atoms: about 320 quintillionths of a second.

The journal Nature publishes this week a study of electronic dynamics ("Direct observation of electron dynamics in the attosecond domain"). The participants of this study, together with other researchers, have been professors Daniel Sánchez-Portal and Pedro Miguel Etxenike from the Donostia International Physics Center (DIPC).
