Modules

Everything taught in a chemistry classroom,
interactive and in-browser.

01

Periodic Table

All 118 elements. Hover animations, trend overlays, electron configurations, electronegativity maps.

HS-PS1-1
02

Molecular Builder

Drag and drop atoms, form bonds automatically, view VSEPR geometry and molecular polarity — live.

VSEPR / Bonds
03

Equation Balancer

Enter coefficients, verify atom counts, revise your setup with clear, immediate feedback.

HS-PS1-7
04

Reaction Kinetics

Animated particle collisions with energy diagrams. Adjust temperature and concentration to watch rate changes live.

HS-PS1-5 / Le Chatelier
05

Nuclear Decay

Alpha, beta, gamma decay with real half-life data from NUBASE. Watch full decay chains and visualize the nucleus.

HS-PS1-8
06

Acid-Base & pH

Interactive pH scale, buffer region visualization, and a full Titration Curve Generator for strong and weak pairs.

AP Chemistry Buffers
07

Gas Laws

Boyle's, Charles', Gay-Lussac's, and Ideal Gas Law with a kinetic particle chamber, P-V graphs, and Van der Waals support.

PV=nRT / HS-PS3-4
08

Chemical Equilibrium

ICE tables, Le Chatelier disturbances, and live Kc calculations. Add reactants and watch the system shift in real time.

HS-PS1-6
09

Stoichiometry Suite

Molar mass reference, conversion checks, guided practice, and solution-prep verification — no auto-filled answers.

Moles / Yield
10

Thermodynamics

Interactive energy diagrams, heat capacity calculator, Hess's Law pathway, and real-state phase change simulation.

HS-PS3-1 / PS3-2

For Educators

Built for real classrooms.

Create and share interactive chemistry assignments inside an approved school deployment. Students work through tasks in the same Atomency interface they already know — no extra student accounts, no district IT overhead.

Drag-and-drop Assignment Builder

Add molecule building tasks, balancing challenges, and open-ended questions. Mix in any order.

District-approved assignment links

Shared through school-approved channels, usable in Google Classroom, email, or a district website.

Built-in anti-cheat mode

Answers stay hidden in assignment mode. Students must input and verify their own work.

Good chemistry software
shouldn't require a school budget.

Built for the students who need it most, not the districts with the biggest IT contracts. Atomency is free, open, and built to run in any browser, on any device, in any classroom. No login required. No license to buy.
