Oganesson (118 Og) is a synthetic element created in particle accelerators, and thus a standard atomic weight cannot be given. Like all synthetic elements, it has no stable isotopes . The first and only isotope to be synthesized was 294 Og in 2002 and 2005; it has a half-life of 0.7 milliseconds.

Oganesson is expected to be rather like silicon or tin in group 14: [53] a reactive element with a common +4 and a less common +2 state, [54] [55] which at room temperature and pressure is not a gas but rather a solid semiconductor. Empirical / experimental testing will be required to validate these predictions.
In general. Usually parameters reproduce the value, and the template adds the SI unit or additional standard text. While the topic is technical, we can strive to make the result readable text, and even verbose.
Interest in a possible island of stability grew throughout the 1960s, as some calculations suggested that it might contain nuclides with half-lives of billions of years. [48] [5] They were also predicted to be especially stable against spontaneous fission in spite of their high atomic mass.
