![]() The abundance in Earth's crust could be interesting. I don't care about who discovered an element when. You might want to restrict to the most common numbers, especially for a smaller table. Most elements have many possible oxidation numbers, check Wiki for that. To the very least, hint at this somewhere, and tell which convention you use. Molar volume and heat capacity are dropaway candidates for a smaller chart. This should at least be hinted somewhere. In some cases, especially graphite, the density is only a theoretical value never encountered. The density, molar volume and specific heat capacity depend on the allotrope. Be clear if "metal" is for a chemist or a solid physicist. Metal, semi-metal, metalloid, transition element. Stable, radioactive, artificial (which isn't the same) I suggest that you shade and circle the element boxes with different colours to indicate I'd like the isotopes listed by decreasing natural abundance, and maybe by decreasing half-life for the unstable ones. At best, you can indicate the decay of the most abundant isotope, but some elements are not natural. Some elements have a dozen natural isotopes and 30 known isotopes, most with 2-3 decay modes. That's a nuclide property that fits in a table of the nuclides. I doubt you can indicate the half-life and decay mode for the elements. This is a matter of taste, and you'll get as many opinions as people. For the smaller size chart, which of the above do you think I should keep or be okay with eliminating? The smaller size will require that I display fewer properties (space is tight). I also had a request for a larger "auditorium lecture" size version, and a smaller-room-size version (28 x 40 inches). Question 2: The chart will be 42 x 58 inches (typical classroom size). Question 1: Are there any additional properties that you would like to see added? year of discovery and the discoverer(s) atomic radius, covalent radius, ionic radius whether the element is gas, liquid or solid In addition to arranging the elements in standard 18-column format and displaying the symbols, numbers and names of the 118 elements, for each element the chart will illustrate: I am hoping to get initial thoughts now, and (down the road) some critiques of the chart itself prior to printing.Īll totaled I'll be displaying more than 20 properties for each element. ![]() The first version will be a printed, classroom-size wall chart. I'm hoping to gather some opinions.Īs part of a STEM/STEAM inspired initiative I am designing a periodic table that will visualize the various properties of the elements, using the best principles of "information design" to illustrate those properties, which will allow the elements, groups and periods to be more clearly understood and compared.
