![]() : Fixed note about gas density to read ". The sum of the oxidation states within a compound or ion must equal the overall charge. In polyatomic ions, the algebraic sum of the oxidation numbers of all the atoms must equal to the charge of that polyatomic ion. Uncombined elements have an oxidation state of 0. The oxidation number of oxygen in a compound is -2, except in peroxides (H 2 O 2) where it has oxidation number of -1. It is defined as being the charge that an atom would have if all bonds were ionic. : Updated the Excel and PDF files to correctly classify Radon as a gas. The oxidation state of an atom is a measure of the degree of oxidation of an atom. Elements toward the bottom left corner of the periodic table are more. : 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). By definition, the oxidation number of an atom is the charge that atom would have. 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.
