![]() Element names in dozens of languages, even Asian scripts. Borders indicate primary decay mode.ĭozens of languages. Hover over to fan through like a deck of cards as 5 properties update including half-life. Click an element in the isotope view to overlay selected or all known isotopes. Hover over each electron pair for a 3-D view of that orbital or hover over the element to view its highest energy level electron pair. Complete orbital readout for each element's ground state, quantum numbers, oxidation states, and diagram following Hund's rules. ![]() All told, the slider area exposes another 17 properties in addition to the 16 shown, not including the first 30 ionization energies, allowing efficiency functioning on multiple levels and in multiple dimensions. After selecting radius, for example, covalent, empirical, calculated, and van der Waals radii are available. Once you've selected a dataset, the slider area reveals related properties. ![]() After selecting discovery year in Properties, use the slider to go back in time and display only the elements discovered by that year.ĭata subsets. Drag the slider above the nonmetals and see the state of matter of each element at that temperature. Translations and foreign element names, however, should be considered no more reliable than Wikipedia. Significant digits are preserved in readouts whenever space permits. When important values disagree with WebElements, which also uses primary sources, we discuss who might be wrong and why, perhaps even leaving our data mismatched so you get the chance to make your own analysis. Our data doesn't come from secondary sources. Does atomic radius go up or down by group? Select it and the color of all elements will change in proportion to their values. Or, maximize and select names and/or electron configs to accompany the dataset you choose. Only want to see one piece of data at a time, like electronegativity? Whatever you choose appears in place of atomic weight while symbol and atomic number stay visible. Select Properties and move your mouse over any element to instantly update 16 properties as well as a detailed view of that element. View as much or as little information as you'd like or your screen allows. Use the check boxes at the top of the page to dynamically switch between simple, with names, with electron configuration, and inline inner transition metals. Element names are even left aligned to facilitate easy scanning even though I find it less aesthetically pleasing. You won't find another periodic table that crams so much information into one page. If you prefer Flash, check out Brian Adams' table.Įverything on one page. Your browser's View, Text Size scales the table up or down as you choose. Highlight and copy data, print, and resize to suit your vision, just like you would with any web page. ![]() This gives all the scalability and accessibility of a normal web page while looking as good as any image or Flash out there. What makes this periodic table different? All HTML. The new domain is just to give you, the regular visitor, something easy to spell, type, and remember. New address? The old address, /periodic, will always work. Where are the Roman numeral group numbers like VIIB? Roman numerals for groups were scrapped in 1984 when Reagan defeated Mondale. Isn't it supposed to be Lanthan ide, not Lanthan oid? No, not according to IUPAC (IR-3.5). Most of the site will continue to function without Internet connectivity. How can I use the site when I'm not online? The best solution at this point is just to load the site in your browser, click around the tabs to cache most of the data, and then activate the Work Offline feature of your browser before revisiting the site. For general chemistry (homework) questions, visit the chemistry forum. If you have a question about this periodic table that's not on this page or you would like to follow up on one of the below questions, contact me.
