Periodic Table Poster, Element Density Chart, Chemistry Wall Art, Science Classroom Print, Chemistry Teacher Gift, STEM Decor

The periodic table, weighed. Under every element, a bar for what one cubic centimetre of it weighs, from hydrogen's near-nothing to osmium.

One cubic centimetre of osmium weighs 22.57 g; the same block of lithium, the lightest solid element, weighs 0.534 g.

WHAT IT IS
Most periodic tables tell you how heavy one atom is. This one also shows how heavy the stuff is: under every element, a bar for the weight of a sugar-cube-sized block, on one scale from the gases to osmium. Densities come from PubChem, the US National Library of Medicine's chemistry database, which cites Jefferson Lab for them. The source is printed along the foot of the chart.

THE DATA
Data: PubChem, US National Library of Medicine (pubchem.ncbi.nlm.nih.gov); densities and atomic weights as cited there from Jefferson Lab, US Department of Energy.
Licensed under Public domain (US government work) (https://www.ncbi.nlm.nih.gov/home/about/policies/).
Changes: Densities drawn to scale, gases in scientific notation to two figures; elements with no standard atomic weight shown as [mass number].
The full citation is printed on the chart.
