Feynmanium

語源

Feynman +‎ -ium.
Named after Richard Feynman, who used a back-of-the-envelope calculation using classical physics to determine that element 137 is the last stably neutrally charged element, as larger elements would need electrons traveling faster than light to become neutral.

名詞

Feynmanium (uncountable)

  1. The hypothetical chemical element with atomic number 137.

使用する際の注意点

This is not (yet) an official designation, but is a nickname used by some members of the nuclear physics community. The element will not have an official name until it is actually discovered.
