• Every element is now open: emission spectra, the complete isotope browser, 3D shell and electron-cloud models, atomic radii, oxidation states, and ionization ladders are free for all 118. • New Chemistry Glossary: 151 terms across nine areas, each with a definition, where it applies, related terms, and a cited source — searchable by term, symbol, or meaning. • The Reaction Library grows from 18 to 68 reactions; every equation and classification traces to a named section of OpenStax Chemistry 2e or IUPAC. • The periodic table adds a 32-column long-form layout and can be colored by block (s/p/d/f) or by state at room temperature. Enjoying Chemistry Explorer? A rating takes a few seconds and helps other students find it.
