First-ever high-resolution images of a molecule as it breaks and reforms chemical bonds

The original reactant molecule that is resting on a flat silver surface is imaged both before and after the reaction, which occurs when the temperature > 90° Celsius. 
The two most common final products of the reaction are shown. The three-angstrom scale bars (an angstrom is a ten-billionth of a meter) indicate that the reactant and product molecules are about a billionth of a meter across...
