Mendelevium could have easily been named Seaborgium due to its discovery. It was fairly difficult to capture and like most elements with numbers beyond 100 is only used in research.
The Godwit is a long-legged, long-beaked migratory bird. They are hard to distinguish between each species and were once considered a delicacy. They are tied to Mendelevium as it required Aqua Regia to prove it wasn’t Fermium and because it was almost called Seaborgium. That’s probably the most stupid chemistry joke I will ever make.
Nobelium is an element with a history almost as grandiose as its name. It had several false discoveries and nine controversies that could make a good TV documentary to fall asleep too. It is close to impossible to produce in large quantities and so most of its properties aren’t fully known.
Ermine (Stoats) are ferret-like creatures that live in most of the northern hemisphere. They were once used for fur and sometimes domesticated by those allergic to both dogs and cats. They were also sometimes considered Nobel and thus their connection to Nobelium.
