At the Natural History Museum our work is based on scientific collecting to support research on the natural world. In our collections we hold naturally occurring chemical elements in many different forms, compounds and combinations, so with many others, we are marking the 150 years since the periodic table was published in 1869 by the Russian chemist Dmitri Mendeleev by celebrating the International Year of the Periodic Table. We are aiming to cover all of the elements in our collections in a blog, starting with osmium, rhodium and iridium.
