The element of Thallium
Is found in group 13,
Named after “thallos”, Greek for “green twig”,
From its spectral line in the green.
Its discoverer is contentious…
Crookes versus Lamy- who won?
Lamy’s premier took place one year after
The work of Crookes in 1861.
Thallium is toxic,
It displaces K+ in a cell,
“The poisoner’s poison”, as it was nicknamed
Possesses no taste and no smell.
Nowadays its uses are few
(Banned from rat poison, for a start)
Although a particular isotope is still used today
To medically image the heart.
About the Author
I’m Zoe and for the last five years I studied for my PhD in synthetic inorganic chemistry at the University of Sheffield, specialising in main group coordination chemistry. I now work as a Specialist Junior Demonstrator in Inorganic Chemistry at the University of Oxford. Alongside inorganic chemistry, I also have interests in spectroscopy and crystallography, and can often be found figuring out how an instrument works or looking at nice crystal structures! Outside of chemistry, I enjoy sport, photography and learning a language.
