The Compound Interest Periodic Table of Data

Periodic Table - Orbitals Dec 2016

Today’s graphic is one that I’ve been working on over the past couple of weeks. Every chemistry classroom has a Periodic Table, but it’s often a drab affair; considering it’s one of the cornerstones of chemistry, I thought I’d attempt to produce a more dynamic looking version. The result is the above table – each element is shown within a circle that contains a variety of data pertaining to that element.

The data shown for each element is as follows:

  • Melting point in degrees celsius.
  • Boiling point in degrees celsius.
  • First ionisation energy in kilojoules per mole.
  • Atomic radius in angstroms.
  • Electronegativity (on the Pauling scale).
  • Density (in grams per centimetre cubed (g/L for gases)).

This data provided is provided mainly with A Level students in mind, hence the use of ˚C for temperature over Kelvin, and kilojoules per mole for ionisation energy over electron volts. I did initially include electron affinity data, but then decided that density would be of more interest. The circle segments are also colour coded, and the intensity of the colour is greater for higher values – thus allowing students to appreciate the trends in some of the different properties. Some of the figures are a little difficult to make out on a computer screen, particularly when the background colour is paler, but it’s intended to be printed at large sizes, so this is likely to be less of a problem.

The first version also includes a diagram to show the order in which electron orbitals fill. I’ve additionally produced a second version of the graphic, which simply states the group names, for more general use. Obviously, this one falls into the ‘transition metal’ trap, where Zn, Cd and Hg are designated as transition metals due to their position, despite the fact that really, they do not fulfill the criteria to be designated as such. However, since this isn’t a concept that is explored until A Level, the below table may still find use as a more general purpose table.

This is something I may eventually revisit (though perhaps not for a little while – it took a fair amount of time!). In the meantime, it’d be great to know your thoughts on both of the tables!

Download s/p/d/f block version of the table here.

Download group names version of the table here.

Both version 1 & version 2 are also available to purchase on the site poster store in A2, A1 & A0 sizes.

Awesome! I love your infographics! =D But I believe there’s a mistake in your table. As far as I know, Osmium is element with the highest density. However, in your table Iridium has density 22.65. I think it should be 22.56.

Hi, thanks! I looked into the Osmium/Iridium densities whilst making the table, and it really is rather confused. Measured densities do seem to indicate that Osmium is slightly more dense, but some research has maintained that the values gained from calculations are more reliable. There doesn’t seem to have been an official confirmation of which is more dense than the other, so I’ve stuck with the more widely used calculated figures for now. All of the other densities are from the calculated values as well, so this ensures the table is consistent. However, I will try and dig a bit deeper and see if I can come to a more satisfying resolution!

I think this is one of the most beautiful periodic tables I’ve seen in awhile! Definitely getting a copy laminated to use in our tutoring area at my college. 🙂

[…] Cigarette smoke contains a huge number and range of organic compounds. Estimates in the past few years state that there are almost 7360 different compounds present, and it is likely that this number could still increase. Of this massive number of compounds, 70 have confirmed carcinogenic activity in humans, and many more are suspected carcinogens. The Compound Interest Periodic Table of Data. […]
