Interactive periodic table showing names, electrons, and oxidation states. Visualize trends, 3D orbitals, isotopes, and mix compounds. Fully descriptive writeups.
Above is an interactive periodic table of the elements. Clicking on one of the types of elements at the top will emphasize those elements in the table and give some information about what those elements have in common.
BY SYMBOL IN AN ALPHABETICAL ORDER. You can click on the column header to sort the table by that column. Click on an element symbol to get detailed facts about the element.
List of chemical elements. 118 chemical elements have been identified and named officially by IUPAC. A chemical element, often simply called an element, is a type of atom which has a specific number of protons in its atomic nucleus (i.e., a specific atomic number, or Z). [1]
Interactive periodic table with element scarcity (SRI), discovery dates, melting and boiling points, group, block and period information.
Chemical Element Properties. For each element, we list atomic number, atomic weight, density, melting point and boiling point. On our property pages you can easily visualize how the different elements compare, and observe the trends across the periodic table. Perfect for chemistry class!
