What synthetic element was named in Dmitri Mendeleev's honor? Mendelevium.

Mendelevium is the synthetic chemical element with atomic number 101 and the symbol Md. It was named for Dmitri Mendeleev, whose periodic table provided the conceptual framework that made the discovery and classification of new elements possible.

The element was first synthesized in 1955 at the University of California, Berkeley, by bombarding einsteinium-253 with alpha particles. The experiment produced only a tiny number of atoms, making mendelevium a striking example of nuclear science conducted one atom at a time.

Mendelevium is radioactive, metallic, and part of the actinide series. It has no practical uses outside basic research because its isotopes are short-lived and can be produced only in very small quantities. It is therefore unlike familiar bulk materials such as iron or copper.

The name was especially notable during the Cold War because the honoree was Russian. The name was accepted in 1955; its chemical symbol was later changed from the proposed “Mv” to “Md.”
