Looking at the numbers in the atomic weight area, we can see that there are about 300-400 acids, and most contain hydrogen, carbon, and oxygen.įormula searching Enter a formula into the slider area search box to find all compounds matching those elements, regardless of the order in which you enter them. Typing acid in the slider area search box dims all but the nonmetals. As you search, elements not in matching compounds will dim. Colors mimic standard stick-and-ball model colors.Ĭompound searching Type the CAS number or name of a compound to find all matching compounds. Elements that do combine will show the number of potential compounds in their atomic weight area. As you narrow your search, other elements that do not form compounds with your chosen elements will dim. Drag them around for better positioning.Ĭompound mixing Click elements in the compounds tab to see possible compounds they form, complete with Wikipedia articles when available. Hover over to fan through like a deck of cards as 12 properties update including half-life. Isotopes 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 that you can drag to rotate or hover over the element to view its highest occupied atomic orbital. Orbitals 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 15 shown, not including the first 30 ionization energies, allowing efficiency functioning on multiple levels and in multiple dimensions. After selecting radius, covalent, empirical, calculated, and van der Waals radii are available. Property subsets Once you've selected a property, the slider area reveals related subsets. Time machine Select discovery year to use the slider to go back in time and display only the elements discovered by that year. State of matter slider Drag the slider above the nonmetals and see the state of matter of each element at that temperature. Translations and non-English element names, however, should be considered no more reliable than Wikipedia. Significant digits are preserved in readouts whenever space permits. Layout and presentation were reviewed by the world's foremost periodic table academic Eric Scerri and match the official layout offered by IUPAC, another standards body Ptable keeps in touch with for new standard atomic weights. Reliable source data Data is acquired from primary sources and curated libraries such as the excellent Wolfram|Alpha. Visualize trends Does atomic radius increase or decrease with group? Select it and the color of all elements will change in proportion to their values. Unit conversions are available when appropriate.Ĭhoose your data Want to see electron configurations for all the elements at the same time? Any selected property replaces atomic weight for all elements in the table. Pages of properties Move your pointer over any element to instantly update properties as well as view a closeup of that element with its electron configuration. As you resize your browser, Ptable resizes with it. Instantly change layouts 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. Read while you browse Want to read about elements while perusing the table? Write-up windows can be torn off or docked to the edges (depending on your pop-up blocker settings) to allow simultaneous use of the table while reading. You'll be able to view properties, isotopes, and mix compounds all while offline. Installable app for offline use Whether on mobile or desktop, you can install Ptable using either "add to homescreen" or on desktop, □ on the right inside of the address bar. Select the top/sidebar buttons in the top right, or click the Ptable logo to hide all properties.ĭark mode Eyes burning from staring at your screen during a late night homework session? Click the dark mode icon in the top right for relief as you power through the night. Side bar or top bar Whether you prefer data above the table, beside it, or seeing the table by itself, Ptable has you covered. Continue reading to learn about all the interesting things Ptable does that make Mendeleev's creation come to life. Ptable shines when used as a true application, more interactive and dynamic than any other. Write-ups are great, and Ptable outsources these to the heavily-curated and quickly-revised Wikipedia. What makes Ptable different? A true web application Many periodic tables describe themselves as "interactive" while offering nothing more than links to pages of data about elements.
