Description
An interactive periodic table: search, states of matter at any temperature, property heatmaps and full element detail. An interactive periodic table in your toolbar. Click the icon and the whole table is there — all 118 elements, current IUPAC names, and no page to load. FIVE VIEWS • Categories — the classic colouring across ten element families • States — solid, liquid or gas at any temperature you choose, 0 to 6000 K • Electronegativity — the Pauling scale as a heatmap • Radius — empirical atomic radii as a heatmap • Ionization — first ionization energy as a heatmap Each heatmap names its property and units below the table, and elements with no measured value stay grey rather than guessing. SEARCH Type a name, symbol, atomic number or family such as "noble" or "alkali". Matches are ringed and everything else dims away. Click any family in the legend to isolate it. ELEMENT DETAIL Click a cell for atomic mass, melting and boiling points in both K and °C, electronegativity, atomic radius, density, first ionization energy, block, year of discovery, electron configuration, a drawn electron-shell diagram and a short note about the element. KEYBOARD Press / to search, arrow keys to move around the table, Enter to open the first match, and Escape to go back. Inside an element, left and right step through neighbouring elements. LIGHT AND DARK One button switches theme. Every family colour, phase colour and heatmap was tuned separately for each theme rather than inverted, and text colour is chosen from each cell's measured brightness so labels stay legible throughout. PRIVACY No accounts, no tracking, no network requests. The extension cannot read or change any web page. Every value is bundled inside the extension and everything runs on your device.
