koaksium

Koaksium is a theoretical element with the atomic number 137, symbolized as Ks. It is part of the hypothetical seventh-row transition metals and the d-block of the periodic table. Koaksium is predicted to have similar chemical properties to its lighter homologues, such as ruthenium and osmium, due to its position in the periodic table. Its electron configuration is expected to be [Rn] 5f14 6d7 7s2, indicating it would be a transition metal with a high atomic mass.

The discovery of koaksium is purely speculative, as it has not been synthesized or detected in nature. Theoretical predictions suggest that koaksium would be highly radioactive, with a very short half-life. Its properties, such as its melting and boiling points, are also subject to speculation due to the lack of empirical data.

Koaksium's existence is based on the periodic table's structure and the principles of quantum mechanics. However, the synthesis of such a heavy element is currently beyond the capabilities of modern technology. The search for koaksium is a topic of interest in the field of nuclear physics and chemistry, but it remains a theoretical element for the time being.
