Atomic Nucleus Builder Oganesson Og-342 is a game of electrons. You start with an atomic nucleus, and you must get as many electrons orbiting it as you can. It's that simple. Try to build the atomic nucleus by putting protons and neutrons, layer by layer. The game is a highly complex, dynamic, and interactive visualization but it is also a surprisingly beautiful work of art, designed to help people who want more creative thinking or who need a change of rhythm.

How to play: Double click to open a layer and single click to place a particle.
