Even though he never won a Nobel Prize, Mendeleev did have an element named after him.

In 1955, a scientist at U.C Berkely created an element with the atomic number 101. In 1963, this element officially became known as mendelevium. He is 1 of only 15 scientists to have an element named after them.

If you were a scientist, what would you like an element named after you to be called?
