Atomency vs MoluCAD

Atomency is a browser-based chemistry and physics learning platform with interactive simulations, virtual labs, an interactive periodic table, worked examples, and teacher tools. Its molecule builder displays VSEPR geometry, bond angles, lone pairs, hybridization, formal charge, and polarity. The site lists 29 browser simulations and 17 guided virtual labs, including calorimetry, spectrophotometry, buffer preparation, galvanic cells, and osmosis. Teachers can create assignments with molecule-building tasks, balancing challenges, and open-ended questions, while answers remain hidden in assignment mode. Assignments can be shared through school-approved links or exported for Google Classroom, email, or a district LMS. Atomency maps learning experiences to NGSS performance expectations and organizes content around AP Chemistry, IB Chemistry, and A-Level topics. Core public tools run in a modern browser without installation. Public individual exploration is free at free; official school or district adoption, required coursework, pilots, and managed deployment require a paid license or written authorization.

MoluCAD is a free Windows desktop application for molecular modeling and visualization, designed for chemistry students and originally conceived for organic chemistry study. Users can construct molecular structures in true 3D and inspect them from any viewpoint. The software creates reaction animations and includes more than 170 sample structures and animations that can be opened, viewed, and modified. Built-in MM2 energy minimization supports the modeling workflow, alongside an interactive periodic table and HTML-based help. MoluCAD imports and exports PDB, ENT, MOL, and MM3 files, and generates BMP, JPEG, and AVI files. New River Kinematics offers it as a free download through a Windows executable. The product originated in a three-year National Institutes of Health biomedical technology research project intended to produce low-cost chemistry education software. New River Kinematics, founded in 1994 and based in Williamsburg, Virginia, describes itself as an engineering company developing and supporting portable metrology software solutions.
