This is a periodic table with atomic mass, element name, element symbol, and atomic number. The atomic mass is the average number of protons and neutrons in atoms of a chemical elements, allowing for the natural abundances of the element’s isotopes. This table uses the latest accepted single values because it makes chemical calculations easier. The IUPAC actually recommends a range of atomic mass values for most elements because the isotopic ratio isn’t a constant everywhere on Earth. While a range of values is more accurate, it’s not fun choosing a number for calculations!
This table is optimized for displays with resolution 3840×2160 pixels (4K) but can be resized nicely to 1920×1080 (HD) screens with little to no loss in readability. The element squares are slightly separated, so it’s easy to distinguish between the elements and their information. Click the image above or download the image directly to get your own copy.
There is a PDF version of this table if you’d like to print up a copy. If you choose “Fit to Paper” and your printer will scale the table down without any loss of readability.
