Modules

Everything you need to teach & learn chemistry

Every module is built on real science, targets specific NGSS performance expectations, and can be dropped directly into an assignment.

01
Periodic Table
All 118 elements with hover animations, trend overlays, electron configurations, and electronegativity maps.
HS-PS1-1TrendsConfigs
02
Molecular Builder
Drag and drop atoms, form bonds automatically, view VSEPR geometry, and inspect polarity — all in real time.
VSEPRBondsGeometry
03
Equation Balancer
Enter coefficients yourself and verify your answer. Built as a checker — not a calculator — to reinforce learning.
CheckerHS-PS1-7
04
Reaction Kinetics
Animated particle collisions with energy diagrams. Adjust temperature and concentration to see rate changes live.
HS-PS1-5Le Chatelier
05
Nuclear Decay
α, β, γ decay with real half-life data. Watch full decay chains, track isotope changes, and visualize the nucleus.
HS-PS1-8Half-life
06
Acid-Base & pH
Interactive pH scale, buffer region visualization, and a full Titration Curve Generator for strong and weak pairs.
AP ChemBuffers
07
Gas Laws
Boyle's, Charles', Gay-Lussac's, and Ideal Gas Law — with animated particles, P–V graphs, and Van der Waals support.
PV=nRTHS-PS3-4
08
Equilibrium
ICE tables, Le Chatelier disturbances, and live Kc calculations. Add reactants and watch the system shift in real time.
HS-PS1-6ICE
09
Stoichiometry Suite
Molar mass, unit conversion, limiting reagent, percent yield, and molarity — all calculated as you type.

For Educators

Built for real classrooms

Create and share interactive chemistry assignments in minutes. Students work through tasks in the same Atomency interface they already know — no printing, no extra accounts.

01
Drag-and-drop Assignment Builder
Add molecule building tasks, balancing challenges, and open-ended questions. Mix and match in any order.
02
Share via a single URL
No server needed. Every assignment compresses into a shareable link — paste into Google Classroom, email, or a website.
03
Built-in anti-cheat mode
Answers stay hidden in assignment mode. Students must input and verify their own work — they can't just copy the output.

Curriculum Alignment

Mapped to the standards you teach

Every module ties directly to NGSS performance expectations, AP Chem units, IB Chemistry, and A-Level topics.

NGSS HS-PS1-1
Periodic Trends
Predict properties using electron configuration and periodic table position.
NGSS HS-PS1-2
Chemical Reactions
Explain reaction outcomes from electron states and periodic patterns.
NGSS HS-PS1-5
Reaction Rates
Apply temperature and concentration principles to predict rate changes.
NGSS HS-PS1-6
Equilibrium
Increase product yield by applying Le Chatelier's principle to a system.
NGSS HS-PS1-7
Conservation of Mass
Use representations to show conservation of atoms across reactions.
NGSS HS-PS1-8
Nuclear Processes
Model nucleus composition changes during fission, fusion, and decay.
