Intuiitive exploration

I think the app could do with some more explanation/guidance regarding why certain isotopes are stable while others are not, and what governs the shell that electrons preferably "localize" to (quantum superpositioning aside). These are points of curiosity I would have liked to explore further. However, the interface is simple and the visuals are beautiful. Overall a great, intuitive way to explore the structure of the elements. Well done!
