My daughter has been given a middle school project to create a model of a Lithium-6 atom. I thought it would be cool to show the nucleus with a set of six balls representing the protons and neutrons.
However I can't find a decent reference for how we should arrange them. The sources that seem most promising are research papers I don't have access to.
Any ideas? or is this something that scientists haven't actually figured out yet?
The one source we did find that had a diagram was not what I considered reliable.
