Meitnerium is a synthetic element and does not occur in nature. Not enough has been made to know anything about the element's chemistry.

The composer of this block chose to represent meitnerium with an artistic rendition of herself because of certain things she has in common with the element. Not only does she share her initials (MT) with the element's chemical symbol (Mt), but as well, the atomic number, l09, taken as a date (1/09, Jan. 9) is the artist's birthday.
