  1. For a suggestion, I have one strong suggestion for adding a property: Tensile Strength.
    Actually, I would like to make a proposal; I am currently collecting this data for each element in a spreadsheet already.
    When it is done, I would like to show it to you along with sources, so you can consider adding the data to the website's element property.

    First, I would like to try to demonstrate why specifically Tensile Strength is worthy among countless mechanical properties of materials.
    https://en.wikipedia.org/wiki/Strength_of_materials#Stress_parameters_for_resistance
    In an introductory material science paper, it focused heavily on Stress–strain curve, and various testing for material…

  2. Make the rare earth metals only have 14 columns. (57-70 and 89-102) This displays that the angular momentum 3 (f) has 7 magnetic quantum numbers (-3,-2,-1,0,1,2,3), 2 spins each (-1/2, 1/2) = 14 electron capacity. If other words it if you use the periodic table to help you do the electron configuration, instead of the electron tree, it will be correct because the "f block" on the periodic table should only hold 14 electrons.

  4. I teach 8th grade physical science and we use your amazing site regularly. The problem is it has way more information than an 8th grader would need. Is there a way to view a simplified version of all the properties? Many are just not applicable to 8th grade. Easiest way would be to have check boxes so you can select the properties that you want to see at that time

  5. The data is available on Wikipedia:
    https://en.wikipedia.org/wiki/Prices_of_chemical_elements

    It would be great to be able to visualize this data on Ptable.

  6. I would LOVE to have Mendeleev's original table with the option to view the properties, etc. And, there are so many other alternative tables!

    I would be happy to help program this over the summer break.

  7. On my windows pc, whenever I switch to the electrons page on the PT, my computer lags a ton and task manager shows that chrome takes up 90% of CPU usage. This doesn't happen on my iPad or anything so I think it's some sort of windows bug

  9. maybe add important numbers like avagadroes number and the speed of light, and also some diatomic molecules and some polyatomic ions
