Editorial Policy

## Editorial Policy

## How content is made

Every concept page follows a fixed structure: quick answer, learning objectives, intuitive explanation, equations with defined variables, a worked example, common mistakes, applications, FAQ and links to the related calculators and practice. Reference pages — elements, compounds, ions, constants — follow fixed data templates so the same fields appear in the same order on every page.

## Review pipeline

Content passes through drafting, scientific review (formulas, units, stoichiometry, data values and numerical examples), editorial review (clarity, structure) and technical QA (links, metadata, accessibility, performance) before publication.

## What we never do

We never invent formulas, constants, data values, citations, authors, credentials or affiliations. Uncertain content is flagged for human review, not published.

## Updates

Pages carry publication and review dates. Substantive corrections are logged on the Corrections page.
