U.S. Army STARS Elements is a fun and exciting way to learn chemistry. Build your own atom, play a game to help you learn about chemical bonds, explore the periodic table, and test your chemistry knowledge. Elements is great for students, teachers, and anyone interested in chemistry. U.S. Army STARS Elements includes... Atom Builder - A simple, powerful tool that let’s you construct and discover atoms. Add and subtract protons, neutrons, and electrons and see, in 3D, what you can create. SmashBond - Use the octet rule to bond elements and score points in SmashBond. Swap elements to make 2, 3, or 4 element bonds, and grab bonuses to get a SMASHBOND. It’s a really fun way to help you become familiar with the octet rule and learn common chemical bonds by their type, symbol, name and Lewis dot diagram. Periodic Table - Use the table to view trends and detailed information about each of the 118 elements. See an interactive Bohr’s model and learn interesting facts about the elements. It’s like a regular periodic table, but interactive and fun. STARS Challenge - When you’re ready to test your knowledge, take the STARS Challenge. You’ll be presented with questions in 3 areas (elements, bonding, and atomic configuration). Can you master them all? No matter what your level of experience with chemistry, U.S. Army STARS Elements makes learning fun. Easy to use lesson plans and teacher guides are available at http://usarmystars.com/lessons to help integrate Elements into the classroom.

Atomizer AR turns your iPhone or iPad into a portable quantum chemistry lab. Visualize atomic and molecular orbitals in 3D, render electron density clouds, and step into immersive WebXR augmented reality where molecules sit on your desk at real-world scale. — WHAT YOU CAN DO — • Explore atomic orbitals computed from real hydrogenic wavefunctions: 1s, 2p, 3d, 4f and beyond, with adjustable shell glow and Bohmian trajectory animation. • View any molecule's molecular orbitals (HOMO, LUMO, intermediates) computed via PySCF on the cloud, then rendered as interactive isosurfaces. • See ball-and-stick models in WebXR augmented reality. Tap "View in AR", point at a flat surface, place the molecule on a table, then pinch to scale and drag to rotate. • Pair your phone with the desktop using Atomizer Remote: enter a 4-letter code, then tilt your phone to control the on-screen molecule with your gyroscope. Live preview streams back to your phone in real time. • Browse 40+ molecules — water, glucose, caffeine, benzene, ammonia, ethanol, methane, sulfuric acid and more — with energy diagrams, dipole arrows, lone pairs (VSEPR) and MO correlation diagrams. • Calculate molar mass live from any chemical formula, including parenthesised groups like Ca(OH)₂ and (NH₄)₂SO₄, with per-element breakdown. • Balance equations, run stoichiometry, sketch molecules in 2D, and explore reaction pathways. — SUBSCRIPTIONS — Free: 5 molecule renders per period. All calculator tools and full periodic table. Californium Pass — $2.99/month. 50 renders monthly, priority compute queue. Einsteinium Pass — $6.99/month. Unlimited renders, GLTF export for AR/3D printing, protein visualization, priority support. Auto-renews unless cancelled at least 24 hours before the period ends. Cancel anytime in Settings → Apple ID → Subscriptions. Subscriptions sync across iPhone, iPad, and electronvisual.org.
