Great use of Tech!

This app is super cool! I love the high definition graphics and interactive nature! This is a great app to use in my classroom to teach my students about the periodic table. Students add protons, neutrons, and electrons to make the different elements on the periodic table. As they create these elements the app instructs them about how elements are created and demonstrates what happens if elements become unbalanced. As the participant creates the element it is placed on the periodic table. Participants unlock each element as they build it! The free version only allows you to create the first 56 elements, but it would be a great buy for anyone using this app for science instruction/learning. After the element is created it also gives you characteristics and info about the element. Great science find!!

Very cool

Excellent graphics, great learning aid, and the explosions are fun!

Why put nonsense games on your phone for your kids, when you can put this app & Star Chart on it & add some inadvertent education when they get their screen time?

With modern tech offering so many options to consume your time (and money) with nothing to show for it but the passage of time, it's really satisfying when your elementary-age kid comes up to you & asks for your phone to play Nuclear or Star Chart, especially when other electronic gaming options are around for them. (on Mom's phone, even)

Future enhancements to think about:
• have the decay "explosions" reflect some relative, approximate amount of binding energy released. (Currently all decays look pretty much the same.)
• I don't know how this works, but presently you can add electrons to an isotope until the cows come home (or until it decays.)
• I think it would be interesting to see some indication of effort needed to add each additional partial. (Ideally, the user would have to >exert< a relative amount of energy appropriate & proportionate to the addition, but I have no idea how this could be implemented.). For an indication of energy consumed to add a particulate, I'd suggest some spectrum/thermometer bar indicator deftly harmonized into the display.

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!
