To date, 118 chemical elements have been found. Professor Mario Markus, Max Planck Institute for Molecular Physiology, Dortmund, Germany, takes a look at each element, presenting a poem based on its natural properties along with a scientific overview of each element.

All 118 poems – as well as some poems about elements that only exist in theoretical simulations – are published in the book Chemical Poems: One On Each Element by Mario Markus. ChemViews magazine will publish a selection of these poems over the next months.




Silvery metal. Density: 6.97 g/cm³. It was discovered in 1878 by the
Swiss scientist Galissard Charles de Marignac in the mineral Gadolinite.
The name comes from Ytterby, a mine in Sweden where ytterbium,
terbium, erbium, and yttrium were first found in minerals.

Its electrical resistance increases tenfold when raising the pressure
from 16,000 to 40,000 atmospheres, and suddenly falls to one hundredth
of the value when the pressure is further increased [1]. This
property of ytterbium has been used to measure pressure waves due
to nuclear explosions, for example of the bombs “Trinidad”, “Little
Boy” and “Fat Man” in 1945, “Hurricane” in 1952 and “Smiling Buddha” in 1974.

The instant
that appears
without existing,
as no one could witness
its passage.
And there are
neither verbs
nor adjectives,
for the mouth of the giant
that pronounced them
fell to pieces.
The moment of “Fat Man”,
“Smiling Buddha”,
“Little Boy”.

The instant
in which Ytterbium,
hidden in the mountain,
tells us that death
forty thousand
