Pretty cool, sometimes looking at galaxies I think of the electron dance around the atoms.

Saw this yesterday. Can't play that one either. Here's one that does for me.
Pretty cool!

spacemunkee your video does load better

 you can see the difference in the type of bonding those 2 atoms are doing, sometimes sharing electrons and sometimes merging to become one molecule with a shared electron cloud

I was not able to get the second video to play either.

 

Here's another.

I got the second link to play.

 

Question, if two atoms of the same element bind, is that a molecule? Or, something else?

Pretty sure there's a visible quantum leap jump in that video, if it's uninterrupted sequential.

Question, if two atoms of the same element bind, is that a molecule? Or, something else?

Yes.  Think of a molecule of Oxygen, O2, one of Nitrogen, N2, and of course Hydrogen, H2.

 

The question is more complex when it comes to metals and crystalline substances, since with metallic bonds there's no clear boundaries to the molecule.  It's just a pattern of individual atoms bonded over trillions of connections.

 

Crystals form unit cells, which are not quite the same as molecules since they're dependent on their neighbors for their structure.    A molecule of silicon dioxide, for example, SiO2, becomes a tetrahedon of SiO4,  but the oxygen atoms are going to be shared with other surrounding silicons so that the aggregate composition is SiO2, yet every silicon atom will still be associated with 4 oxygens.  Adding in other atoms such as aluminum, iron, magnesium, calcium, etc., only makes the structure ever more hideously complex.  In these cases the actual identity of a "molecule" can be rather blurred.
