For fictional and conspiracy references to element 115, see Materials science in science fiction. Chemical element with atomic number 115 (Mc) Moscovium, 115 Mc Moscovium Pronunciation / m ɒ ˈ s k oʊ v i ə m / (mos- SKOH -vee-əm) Mass number (data not ...
To give provisional names to his predicted elements, Dmitri Mendeleev used the prefixes eka- / ˈ iː k ə-/, [note 1] dvi- or dwi-, and tri-, from the Sanskrit names of digits 1, 2, and 3, [3] depending upon whether the predicted element was one, two, or three places down from the known element of the same group in his table.
In his later years, Ghiorso continued research toward finding superheavy elements, fusion energy, and innovative electron beam sources. He was a non-participating co-author of the experiments in 1999 that gave evidence of elements 116 and 118, which later turned out to be a case of scientific fraud perpetrated by the first author, Victor Ninov .
Moscovium (115 Mc) is a synthetic element, and thus a standard atomic weight cannot be given. Like all synthetic elements, it has no known stable isotopes. The first isotope to be synthesized was 288 Mc in 2004. There are five known radioisotopes from 286 Mc to 290 Mc. The longest-lived isotope is 290 Mc with a half-life of 0.65 seconds.
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.

[26] [27] Based on the theoretically predicted cross section, it was expected that an ununennium atom would be synthesized within five months of the beginning of the experiment. [28] Moreover, as berkelium-249 decays to californium -249 (the next element) with a short half-life of 327 days, this allowed elements 119 and 120 to be searched for ...
It was apparently discovered by the fictional Thomas Kyle, who was awarded an Ig Nobel Prize for physics for his discovery, [10] and it is a parody on bureaucracy of scientific establishments and on descriptions of newly discovered chemical elements. Administrontium Scientific in-joke: Similar to Administratium and a variation of the joke. It ...
