ätium
ätium is a hypothetical element with the symbol Ä and atomic number 137. It is not a naturally occurring element and has not been synthesized or observed. The concept of ätium arises from theoretical considerations in physics, particularly related to the fine-structure constant, often denoted by the Greek letter alpha ($\alpha$). The value of $\alpha$ is approximately 1/137.
In some speculative theories, a strong interaction between fundamental particles could theoretically lead to the creation
The idea of element 137 is therefore more of a theoretical curiosity or a thought experiment within
