Frequently Asked Questions
Where do the periodic table data and atomic masses come from?
Our data is carefully sourced from IUPAC standards and international chemical references. However, if you find any discrepancies, please let us know.
How does the Molecule Helper calculate geometry?
The Molecule Helper uses standard VSEPR theory algorithms to determine the electron and molecular domains around the central atom, generating standard angles (e.g. 104.5 degrees for H2O).
I have a feature request (e.g. stoichiometry calculators)!
We are always expanding Chemify. We love hearing from our users! Email us at support@twotypestudioapp.com and let's discuss adding it.
