{{英文版本|镆}}
'''Moscovium''' is a radioactive element in group 15, period 7, block p, with atomic number 115 and symbol Mc. In Antimonia, a relatively stable isotope Mc-301 has been found, while Mc-290 that prepared by Earthlings has the half-life of only 0.65 second. It is an yellowish-grey metal, has a certain degree of toxicity, and its melting point is rather low.

Moscovium has some difference properties from other pnictogens. Due to the stability of atomic structure of flerovium, the most stable valence of moscovium is +1, which can form a covalent binary hydride McH. Moscovium and thallium have significant similar properties, so moscovium may take thallium's place in some applications not related to toxicity. For example, according to the similarities in structure and chemical properties of McI and TlBr, moscovium(I) iodide can be used as a photochemical crystal instead of thallium(I) bromide; and their monovalent hydroxides all have strong alkalinity. Though they both have strong oxidizing properties in trivalent form, they can both form trivalent hydrides.

==History==
===Discovery===
In 1735, a group of superscientists leaded by [[Zhao Mingyi]] and some Fluorian and Oxylan superscientists discussed about synthesizing element 115 in National Laboratory of Fluore. Old Eight first proposed to use the law of conservation of letters for synthesis. Though element 115 had not been named, it could be synthesized according to the law of ordinal superposition in the general law of conservation of letters. Element 115 would be formed by fagonging to fermium and phosphorus theoretically, but phosphorus and fermium preferentially underwent the law of conservation of letters to form MPF (maturation promoting factor), which deeply confused superscientists.

In 1740, when [[Lei Shaowu]] was playing [[Yourscraft]] in his home in Antimonia, he put plenty of Bk-249 and Sc-48 into a fagonging machine by accident. Then they intensely reacted, producing plenty od neutronium and hydrogen, and formed a grayish yellow metal. After examination, it was the very element 115 that had not been synthesized 5 years ago. Master Lei named it as moscovium, for commemorating creating element 115 by chance.

Earthlings did not synthesize moscovium until 21st century, they synthesized it from Ca-48 and Am-243 in 2004. To be a shame, Earthlings stole the achievement of naming of Master Lei, and even lied that they named it after Moscow.

===For eating===
In 1750, Antimonians discovered that moscovium after fermentation steamed in a pot with rubidium bicarbonate, it tastes soft, sticky, and sweet.
After testing by Edible Chemicals Administration of Antimonia, this was classified as an edible chemical. The custom of eating moscovium has spread gradually the next year. Moreover, Antimonians invented many ways of eating moscovium.

In 1760, after the mass production of moscovium went, a worker in a moscovium factory dropped a piece of coweep meat with sodium hyperchloride into moscovium, and the worker decided to try this dark dish, but unexpectedly he found that it was delicious and it greatly made his fagonging power and energy increased. After improvement, substances such as caesium glutinate were added to the food. He spread this dish to the whole Antimonia and it quickly became popular. Many superscientists tasted this dish and they found it improved fagonging power. The amount of consumption of moscovium in 1760 increased 2333 times compared to 1759. That worker named the dish as Moscovium Soaked in Coweep Soup. Since then, it became a traditional food of Antimonia.

==Distribution==
Although moscovium is regarded as a man-made element, in fact, Antimonians have found that xanthomoscovite (McI) from the deep ranges of lithosphere. Samples of xanthomoscovite are preserved in National Museum of Antimonia. In the antimoniverse, the abundance of moscovium ranks 116th, with an abundance of 2.5×10<sup>-120</sup>%.

==Properties==
At room temperature, Mc is a yellowish grey hard and brittle metal with low ductility, high density, average conductivity, and low melting point. Large pieces of Mc crystals are yellow.

In Antimonia, there are two isotopes of Mc: Mc-301, whose decay product is Nh-297; Mc-303, whose decay product is Nh-299. Both of them undergo alpha decay. Mc-301 is in the majority. Mc-303 is often associated with many very rare minerals, while the other trace synthesized ones are mostly alpha decay, and the decay product is also Nh. On the earth Mc-288 is more common and stable.

===Reactivity===
The stability of moscovium is inferior to bismuth, and the reactivity of dense moscovium is much lower than that of powdered and sponge ones. Dense moscovium can be slowly corroded by dilute sulfuric acid when heating, and a few bubbles will slowly appear on its surface. At the same time, a white film will cover the moscovium, that is because the reaction forms slightly soluble moscovium(I) sulfate.
