Periodic Table PDF: Electron Affinity Heat Map

What is on it

Every element shaded by electron affinity in kJ/mol, on a linear scale, with darker tiles for a stronger pull on an extra electron. The printed value is on each tile and tiles with no data are grey. The highest is chlorine (348.6) and the lowest is nobelium (-2.2 × 10²).

Best for

Comparing which elements gain electrons most readily, and why the halogens stand out.

Printing tips

Heat maps rely on shading, so print in color. In grayscale the darker tiles still read as higher values.

Periodic Table PDF: Thermal Conductivity Heat Map

What is on it

Every element shaded by thermal conductivity in W/m·K, on a logarithmic scale, so the poor and good conductors can be compared. The printed value is on each tile and tiles with no data are grey. The highest is silver (429) and the lowest is radon (3.6 × 10⁻³).

Best for

Comparing how well elements conduct heat, and seeing why metals are used for cookware and heat sinks.

Printing tips

Heat maps rely on shading, so print in color. In grayscale the darker tiles still read as higher values.

Periodic Table PDF: Abundance in the Earth's Crust Heat Map

What is on it

Every element shaded by abundance in the Earth's crust in mg/kg, on a logarithmic scale, because the values span many orders of magnitude. The printed value is on each tile and tiles with no data are grey. The highest is oxygen (461,000) and the lowest is protactinium (1 × 10⁻⁶).

Best for

Showing which elements make up the Earth's crust and how rare most of the others are.

Printing tips

Heat maps rely on shading, so print in color. In grayscale the darker tiles still read as higher values.

Mendeleev Periodic Table PDF (1869 Original)

What is on it

Mendeleev's first published table, redrawn as printed in the 1869 abstract: his atomic weights and symbols, the German decimal commas, and a dashed outline around the entries marked with a question mark. J is iodine, Ur is uranium, and Di is didymium.

Best for

History of science lessons, and comparing the first arrangement of the elements with the modern table.

Printing tips

Sized for A4 portrait: print at 100% (actual size). Black and white, so it photocopies cleanly.

Mendeleev's Predicted Elements PDF (Eka-Aluminium, Eka-Boron, Eka-Silicon)

What is on it

The eight elements Mendeleev's table predicted, with their modern names and atomic numbers. Eka-aluminium (gallium) and eka-silicon (germanium) are compared property by property with the observed values.

Best for

Showing why the periodic law was convincing: predictions made before the elements were found, then checked.

Printing tips

Sized for A4 portrait: print at 100% (actual size). The header colors are light, so it also prints well in grayscale.
