Scientists filmed a video about two rhenium atoms coming together and moving away from each other in an electron microscope.

In a sequence of images from an electron microscope, two atoms of metallic rhenium, bonded together to create a molecule, first came together, then moved away. The number of chemical bonds between atoms has changed over time. The closer the atoms were to each other, the greater was the number of bonds. With a strong approach, the atoms had four bonds.

To facilitate visualization, scientists have enclosed molecules into carbon nanotubes. But then one molecule accidentally escaped from its conclusion and ended up in the gap between two nanotubes. There, the bond between the atoms has been completely broken.
