Now, let me recall to you the atomic mass of lithium, sodium and potassium. The main thing I want to tell you is that he arranged these elements in the increasing order of their ATOMIC MASS. For best printing, choose Landscape and ‘Fit’ for. This table is available for download as a PDF file and printed for offline use. The most common oxidation states are in bold text and predicted or unconfirmed states are in italics. : Fixed note about gas density to read ". Calcium (Ca), strontium (Sr) and Barium (Ba) in other triad and, Chlorine (Cl), bromine (Br) and iodine (I) in other triad. This color periodic table contains the number, symbol, name, atomic mass and oxidation states of each element. : Updated the Excel and PDF files to correctly classify Radon as a gas. Though individual atoms always have an integer number of atomic mass units, the atomic mass on the periodic table is stated as a decimal number because it is an average of the various isotopes of an element. The modern version of this periodic arrangement is the Periodic Table. : Update (Version 1.1) - Added indicator for radioactive elements, color-coded melting and boiling point data, added the crystal structure (in place of the van der Waals radius), and marked the atomic radius as either the metallic radius (m) or covalent radius (v). Standard Atomic Weight The standard atomic weight is the average mass of an element in atomic mass units ('amu'). Using Cannizzaro's atomic weights, Mendeleev and Lothar Meyer made a great discovery, the periodic law: If you arrange the elements by their atomic weights, there is a periodic repetition in properties such as valence. Tip: You can create your own mini periodic table poster by printing on 11x17 paper. You can use this data table for creating trend charts or use lookup functions to use the data within calculations. If you'd like to create your own personal custom periodic table, you can download this Excel file and add your own sets of properties.ĭata: The spreadsheet also includes a worksheet that lists the property data for the elements. This spreadsheet was used to create the printable periodic table above and also contains a worksheet listing the data for various chemical properties. "No installation, no macros - just a simple spreadsheet" - by Jon Wittwer and Brent Weight Description
