Interactive chemistry tool for visualizing elements and building molecules
Built by Ky'lin Spears for chemistry education
118 Elements • 110M+ Molecular Structures
Interactive chemistry simulation platform built for K-12 education. Covering 118 elements, molecular building, 3D geometry, reaction kinetics, and nuclear decay — all aligned to NGSS HS-PS1 standards.
All 118 elements with hover animations and detailed data panels. Explore atomic mass, electron configuration, electronegativity, ionization energy, and category groupings in an intuitive grid layout.
Build any molecule with drag-and-drop atoms on an interactive canvas. Automatic bond formation based on valence electrons, real-time formula generation, and molecular weight calculation.
3D molecular geometry prediction using VSEPR theory. Atoms snap into correct spatial arrangements — linear, trigonal planar, tetrahedral, and more — with lone pair visualization and bond angle labels.
Deep analysis of built molecules including partial charges, oxidation states, formal charges, and dipole moments. Click any atom to inspect its electronic environment and bonding character.
Save molecular structures as PNG images or JSON data files. Import previously saved molecules with full multi-molecule support. Share your work across sessions and with classmates.
Simulate chemical reactions with adjustable temperature and concentration controls. Animated particle collisions, real-time energy diagrams, activation energy visualization, and Le Chatelier's principle demonstrations.
Visualize alpha, beta, and gamma decay with real half-life data. Watch decay chains unfold in real time, track isotope transformations, and observe how unstable nuclei reach stability.
Select atoms and compounds to see balanced chemical reactions and their physical outcomes. Observe state changes, energy transfer, gas evolution, and precipitate formation.
Atomency covers the full scope of NGSS HS-PS1: Matter and Its Interactions. The table below maps each performance expectation to the specific Atomency features that address it.
| Standard | Performance Expectation | Atomency Feature |
|---|---|---|
| HS-PS1-1 | Use the periodic table as a model to predict the relative properties of elements based on the patterns of electrons in the outermost energy level of atoms. | Interactive Periodic Table — element cards display electron configuration, electronegativity trends, and category groupings with visual color mapping |
| HS-PS1-2 | Construct and revise an explanation for the outcome of a simple chemical reaction based on the outermost electron states of atoms, trends in the periodic table, and knowledge of the patterns of chemical properties. | Molecular Builder + Reaction Builder — build molecules, observe bond formation from valence electrons, and see reaction outcomes with physical state changes |
| HS-PS1-3 | Plan and conduct an investigation to gather evidence to compare the structure of substances at the bulk scale to infer the strength of electrical forces between particles. | Molecule Inspector — partial charges, dipole moments, and electronegativity differences reveal the strength of intermolecular forces |
| HS-PS1-4 | Develop a model to illustrate that the release or absorption of energy from a chemical reaction system depends upon the changes in total bond energy. | Reaction Kinetics Simulator — energy diagrams showing activation energy, enthalpy changes, and exothermic vs. endothermic pathways |
| HS-PS1-5 | Apply scientific principles and evidence to provide an explanation about the effects of changing the temperature or concentration of the reacting particles on the rate at which a reaction occurs. | Reaction Kinetics Simulator — adjustable temperature and concentration sliders with real-time collision frequency and rate visualization |
| HS-PS1-6 | Refine the design of a chemical system by specifying a change in conditions that would produce increased amounts of products at equilibrium. | Reaction Kinetics Simulator — Le Chatelier's principle demonstrations showing equilibrium shifts with temperature and concentration changes |
| HS-PS1-7 | Use mathematical representations to support the claim that atoms, and therefore mass, are conserved during a chemical reaction. | Molecular Builder + Reaction Builder — real-time atom counts, molecular weight calculations, and balanced equation display demonstrate conservation of mass |
| HS-PS1-8 | Develop models to illustrate the changes in the composition of the nucleus of the atom and the energy released during the processes of fission, fusion, and radioactive decay. | Nuclear Decay Simulator — alpha, beta, and gamma decay visualization with real half-life data, decay chains, and nucleus composition tracking |
