How to make an atom like animation using CSS3 animations?

Question

I\'ve being trying this since 3-4 days but am not able to get how do I make this animation, not even sure whether is possible to make one like this using only CSS3?

Answer 1

I think this one also looks like what you asked for but they said it is for Safari only animation as of Chrome 9

You might find a solution with Jquery if you care about browser compatibly.
