We present here a powerful method providing simultaneous atomic spatial and nanosecond temporal resolution for investigating dynamics and structure on the atomic scale, in general. We reveal the dynamic reorganization of surface (ad)atoms induced by radio frequency alternating charging and decharging of a metal. Our method utilizes taylor-made nano-fabricated two-dimensional islands of physisorbed argon atoms, acting as motion sensors, probed by a radio frequency low-temperature scanning tunneling microscope.
