Storm Zeus

🧪 Storm Zeus is a molecule workbench. Type a chemical species — like H₂O, CO₂, Ca(NO₃)₂, CuSO₄·5H₂O, or SO₄²⁻ and it instantly computes everything that follows from that species' composition and structure.

🔬 WHAT IT COMPUTES

⚖️ Molar mass, with each element's contribution (g/mol) and mass-% composition

🧩 Empirical formula, reduced to the smallest whole-number ratio

📐 Degree of unsaturation for neutral C/H/N/O/halogen formulas

⚡️ Net charge, with clear ion/neutral detection

🧬 For single-central-atom molecules and ions, a full Lewis/VSEPR read: total valence electrons, steric number, electron-domain and molecular geometry, ideal bond angle, polarity, formal charges and a bond inventory

The parser respects chemistry 🧠: symbols are case-sensitive (Co is cobalt, CO is carbon + oxygen), and it understands subscripts, ( ) and [ ] groups, hydrate dots 💧 and trailing charges. When something is out of scope it says so plainly, it never invents a number or fakes a geometry.

📚 YOUR COLLECTION

Save the species you care about into a personal collection ⭐ Give each one a label 🏷️ and notes 📝 attach a sample photo 📷 and export a shareable property card 📄 formula, molar mass, composition and geometry, straight to your gallery.

🧮 BENCH CALCULATORS

Reuse any species' molar mass and composition across four practical tools:

⚖️ Mole ↔ Mass ↔ Particles

🧪 Solution & Dilution — grams to weigh out, plus C₁V₁ = C₂V₂

🔍 Empirical Formula Finder — from masses or mass-%

🧫 Element-in-a-Sample — grams and moles of an element in a given mass

🌙 BUILT FOR CLARITY

🌑 One calm, dark theme tuned for reading numbers

⚙️ Adjustable molar-mass precision, formula notation (Hill or as-entered) and particle-count format

🚀 Six example species included, so it's useful the moment you open it

Whether you're studying 📖 teaching 👨‍🏫 or just working through formulas 🧪 Storm Zeus gives you a fast, trustworthy read on any species you can write.
