Molecular Modeling for Education
Build molecules, balance equations, model nuclear decay, and explore all 118 elements — directly aligned to NGSS HS-PS1 standards. No login. No install. Works on any school Chromebook right now.
Built on fundamental equations that power real-world chemistry research and education.
Calculate reaction rates and temperature dependence. Model activation energy and pre-exponential factors for chemical kinetics.
k = A * e^(-Ea / RT) // Rate constant calculation // Ea: activation energy (J/mol) // T: temperature (K)
Predict molecular shapes using Valence Shell Electron Pair Repulsion theory. Visualize bond angles and electron domains.
geometry = VSEPR(electrons, bonds) // Linear: 180deg // Trigonal: 120deg // Tetrahedral: 109.5deg
Simulate radioactive decay processes. Calculate half-lives, decay constants, and daughter nuclei production.
N(t) = N0 * e^(-lambda*t) // lambda = ln(2) / t_half // Alpha, Beta, Gamma decay // Isotope transmutation
Analyze molecular speed distributions. Understand gas behavior and temperature effects on particle velocities.
f(v) = 4*pi * (m/2*pi*kT)^(3/2)
* v^2 * e^(-mv^2/2kT)
// Distribution at temperature T
Everything you need for comprehensive chemistry education in one platform.
Interactive periodic table with detailed element data, electron configurations, and isotope information.
Construct molecules atom by atom. Real-time validation of bonding rules and molecular stability.
Build a molecule and share it as a URL. Anyone who opens the link sees the exact same structure — serverless, no account needed.
Simulate chemical reactions with adjustable temperature, concentration, and catalyst parameters.
Model radioactive decay chains. Visualize alpha, beta, and gamma emission processes.
Molecular weight, bond angles, polarity, estimated boiling point, and bonding summary — all calculated live from the structure you build.
Every module maps to Next Generation Science Standards for seamless classroom integration.
Use the periodic table as a model to predict the relative properties of elements.
Construct explanations of the outcomes of simple chemical reactions.
Apply scientific principles to design, evaluate, and refine solutions for reaction optimization.
Develop models to illustrate changes in nuclear composition during decay and fission.
Atomency works in your browser right now. Build a water molecule in 10 seconds.
Launch Lab NowI built Atomency because I kept running into the same problem in chemistry class. The concepts that actually matter — bonding angles, electron behavior, molecular geometry — are completely invisible. Every tool either cost money the school didn't have, needed IT approval, or just wasn't built for how chemistry is actually taught.
So I built something that works on a school Chromebook, requires zero setup, and is directly aligned to the NGSS standards we're actually graded on. No subscription. No login. No friction.
