element 115 antimatter
[2] Because of spin-orbit coupling, flerovium may display closed-shell or noble gas-like properties; if this is the case, moscovium will likely be typically monovalent as a result, since the cation Mc+ will have the same electron configuration as flerovium, perhaps giving moscovium some alkali metal character. It is classified as a metal and is expected to be solid at room temperature. [2] Moscovium(III) fluoride (McF3) and thiozonide (McS3) should be insoluble in water, similar to the corresponding bismuth compounds, while moscovium(III) chloride (McCl3), bromide (McBr3), and iodide (McI3) should be readily soluble and easily hydrolyzed to form oxyhalides such as McOCl and McOBr, again analogous to bismuth. About 100 atoms of moscovium have been observed to date, all of which have been shown to have mass numbers from 287 to 290. Fresh evidence emerges for superheavy element 115, Tyler Glockner interviews Bob Lazar (Dec 2018), "IUPAC Announces the Names of the Elements 113, 115, 117, and 118", https://iupac.org/iupac-announces-the-names-of-the-elements-113-115-117-and-118/, Scientists Create and Add Elements 113 and 115 to Periodic Table, https://ufo.fandom.com/wiki/Element_115?oldid=23601. [50], In May 2016, Lund University (Lund, Scania, Sweden) and GSI cast some doubt on the syntheses of moscovium and tennessine. New evidence revives controversial idea. Will our solar system survive the death of our sun? Possible drawbacks are that the cross section of the production reaction of 295Ts is expected to be low and the decay properties of superheavy nuclei this close to the line of beta stability are largely unexplored. No properties of moscovium or its compounds have been measured; this is due to its extremely limited and expensive production[16] and the fact that it decays very quickly. [47], In 2011, the Joint Working Party of international scientific bodies International Union of Pure and Applied Chemistry (IUPAC) and International Union of Pure and Applied Physics (IUPAP) evaluated the 2004 and 2007 Dubna experiments, and concluded that they did not meet the criteria for discovery. It enables those reactors - which have been described to be the approximate size of a basketball - to be 100% efficient (with no byproduct). [2], The chemistry of moscovium in aqueous solution should essentially be that of the Mc+ and Mc3+ ions. The decay chains assigned to 289Mc, the isotope instrumental in the confirmation of the syntheses of moscovium and tennessine, were found based on a new statistical method to be too different to belong to the same nuclide with a reasonably high probability. Bill Uhouse Area 51 Alien Underground Base from Bases 2. [2] Both moscovium(I) and moscovium(III) should be common oxidation states and their relative stability should depend greatly on what they are complexed with and the likelihood of hydrolysis. [74][75] In 2011, experiments were conducted to create nihonium, flerovium, and moscovium isotopes in the reactions between calcium-48 projectiles and targets of americium-243 and plutonium-244. However, notable differences are likely to arise; a largely contributing effect is the spin–orbit (SO) interaction—the mutual interaction between the electrons' motion and spin. [5], In 1979, IUPAC recommended that the placeholder name for 115, a then unnamed and undiscovered element (See Mendeleev's predicted elements), be called ununpentium (with corresponding symbol, Uup)[6] until the discovery of the element is confirmed and a permanent name is decided. [19][d], The beam passes through the target and reaches the next chamber, the separator; if a new nucleus is produced, it is carried with this beam. [75] The produced nuclides bismuth-213 and polonium-212m were transported as the hydrides 213BiH3 and 212mPoH2 at 850 °C through a quartz wool filter unit held with tantalum, showing that these hydrides were surprisingly thermally stable, although their heavier congeners McH3 and LvH2 would be expected to be less thermally stable from simple extrapolation of periodic trends in the p-block. [2] Moscovium would be quite a reactive metal, with a standard reduction potential of −1.5 V for the Mc+/Mc couple. Moscovium has four isotopes with known half-lives, the most stable of which is 289Mc, with a half-live of about 220 milliseconds. Lazar claims he examined an alien craft that ran on an antimatter reactor powered by element 115, which at the time had not yet been synthesized. Computation chemists see the split as a change of the second (azimuthal) quantum number l from 1 to ​1⁄2 and ​3⁄2 for the more stabilized and less stabilized parts of the 7p subshell, respectively. However, its range is very short; as nuclei become larger, its influence on the outermost nucleons (protons and neutrons) weakens. It could plausibly be synthesized as the daughter of 295Ts, which in turn could be made from the reaction 249Bk(48Ca,2n)295Ts. [5][42], The hypothetical isotope 291Mc is an especially interesting case as it has only one neutron more than the heaviest known moscovium isotope, 290Mc. It is a member of the 7th period and is placed in group 15 as the heaviest pnictogen, although it has not been confirmed to behave as a heavier homologue of the pnictogen bismuth. He also claims to have read US government briefing documents that described alien involvement in human affairs over the past 10,000 years. Tim Sharp - LiveScience Reference Editor [2] Mc3+ should be about as stable as Tl3+ and hence should also be an important part of moscovium chemistry, although its closest homolog among the elements should be its lighter congener Bi3+. Unlike the two previous 7p elements, moscovium is expected to be a good homologue of its lighter congener, in this case bismuth. The first two of these are relativistically stabilized and hence behave as inert pairs, while the last is relativistically destabilized and can easily participate in chemistry. It was also found that the claimed link between the decay chains reported as from 293Ts and 289Mc probably did not exist. [72] In the predicted aromatic pentagonal planar Mc−5 cluster, analogous to pentazolate (N−5), the Mc–Mc bond length is expected to be expanded from the extrapolated value of 156–158 pm to 329 pm due to spin–orbit coupling effects. You will receive a verification email shortly. Two nuclei can only fuse into one if they approach each other closely enough; normally, nuclei (all positively charged) repel each other due to electrostatic repulsion. [63], Other possibilities to synthesize nuclei on the island of stability include quasifission (partial fusion followed by fission) of a massive nucleus. Dordrecht, The Netherlands: Springer Science+Business Media. [44] Furthermore, the decay properties of all the nuclei in the decay chain of moscovium had not been previously characterized before the Dubna experiments, a situation which the JWP generally considers "troublesome, but not necessarily exclusive". [2] Moscovium should be a dense metal due to its high atomic weight, with a density around 13.5 g/cm3. [2] Moscovium(I) hydroxide (McOH), carbonate (Mc2CO3), oxalate (Mc2C2O4), and fluoride (McF) should be soluble in water; the sulfide (Mc2S) should be insoluble; and the chloride (McCl), bromide (McBr), iodide (McI), and thiocyanate (McSCN) should be only slightly soluble, so that adding excess hydrochloric acid would not noticeably affect the solubility of moscovium(I) chloride. [22] The transfer takes about 10−6 seconds; in order to be detected, the nucleus must survive this long. In Morss; Edelstein, Norman M.; Fuger, Jean. This study criticized the JWP report for overlooking subtleties associated with this issue, and considered it "problematic" that the only argument for the acceptance of the discoveries of moscovium and tennessine was a link they considered to be doubtful.
