Moselium is the fabricated name of an undiscovered element with the symbol Ms and atomic number 123. Moselium was named in honor of Henry Moseley (1887–1915), who discovered the atomic number and reordered elements on the periodic table. This element is known in scientific literature as unbitrium (Ubt), or simply element 123. Moselium is the third element of the lavoiside series and located in periodic table coordinate 5g3.

This element has an alternative name vandenbroekium (Vb), honoring Antonius van den Broek (1870–1926), who was the first to realize that the element numbers in the periodic table corresponds to the charge of its nucleus, which was tested by Moseley in the concept of atomic number.

Properties Edit

Physical Edit

Moselium is a yellowish gray metal that shows goldish luster. Its density is more than 1812 g/cm3 and sound travels through the thin rod of metal at 970 m/s. Liquid moselium is stable from 1530°R to 4720°R; it exists in the solid state below the range while it is gaseous above the range. In the solid state, moselium forms face centered cubic that transforms to rhombohedral upon cooling to 227°R and to base centered cubic upon heating to 910°R. At room temperature, the average atomic separation is 3.10 Å, but distance between atoms increase upon heating while they decrease upon cooling. Because of this, the substance grows upon heating while it shrinks upon cooling, a phenomenon known as thermal expansion.

Moselium is diamagnetic like adjacent elements, meaning it repels in the presence of magnetic field, causing levitation when laying on the surface. Below 22°R, moselium is superdiamagnetic (a property of superconductor), meaning magnetic permeability is completely nil.

Atomic Edit

Moselium contains 123 electrons that are balanced by 123 protons to make the atom neutral. Moselium is expected to have three electrons in the 5g orbital, but due to relativistic effect, there are actually no electron in the g-orbital, but there is one in f-, d-, and p-orbitals. In addition to protons in the nucleus, there are 208 neutrons, corresponding to its mass number 331 and nuclear ratio 1.69.

Moselium atom sizes at 183 pm, 1.83 Å) in radius, which is 22000 times larger than its nucleus in radius, whose value is 8.27 fm (0.0000827 Å). Its bond length, the distance about halfway between moselium and another atom in a compound, is 178 pm (1.78 Å).

Isotopes Edit

Like every other elements heavier than lead, moselium has no stable isotopes. The most stable isotope is 331Ms with a long half-life of 736 million years. It alpha decays to 327Ls. All of the remaining isotopes have half-lives less than 4400 years and the majority of these have half-lives less than five months.

Moselium has several meta states like every other element since calcium. The longest lived is 323mMs with a half-life of just 5 seconds, followed by 3 seconds for 328mMs, and then 130 milliseconds for 329mMs.

Chemical Edit

Since moselium has no electrons in the g-orbital but at least one beyond the g-orbital, the most stable oxistate is +5 to achieve electron configuration of copernicium plus filled 7p3/2 suborbital and one each in 6f and 7d orbitals. Ms5+ needs to bond to elements carrying negative ions totalling to this magnitude to neutralize it, forming pentavalent compounds. For example, Ms5+ needs to bond to five halide ions which carry −1 to form a neutral compound. The bond between positive ion and negative ion is known as ionic bond.

There are also two more, less stable oxistates of moselium, +3 (trivalent) and +4 (tetravalent). Moselium forms +3 state in the Ms3+, which has the electron configuration of [Mc] 6f1 7d1, while Ms4+ has the configuration [Mc] 6f1.

Moselium would be very reactive due to its unique electron arrangement and would quickly lose luster when exposed to air. It would react with water to form a hydroxide, acids to form salts, and organic compounds to form organomoselium compounds.

Compounds Edit

Moselium can form numerous compounds. Moselium(V) oxide (Ms2O5) is a gray solid formed when metal tarnishes in the air that contains portions of oxygen. Moselium(V) hydroxide (Ms(OH)5) formed when metal reacts with water. Moselium(V) sulfate (Ms2(SO4)5) is a crimson precipitate when moselium reacts with sulfuric acid.

Moselium reacts most vigorously with halogens or corresponding acids. The examples are moselium(III) chloride (MsCl3), moselium(V) chloride (MsCl5), moselium(III) bromide (MsBr3), and moselium(V) iodide (MsI5).

Moselium(III) nitride (MsN) formed when moselium reacts with pure nitrogen or ammonia. Moselium can form refractive solids when bonded to boron. Moselium(III) boride (MsB) is a greenish black refractive solid with the melting point of 5998°R, while moselium(V) boride (Ms3B5) is a black refractive solid with the melting point of 7351°R. Pinkish white moselium(V) sulfide (Ms2S5) form when moselium reacts ever with powdery sulfur or hydrogen sulfide. Moselium(IV) carbide (MsC), like borides, is a refractive solid with high melting point. There are three species of moselium hydrides: MsH3, MsH4, and MsH5, all of which are colorless gases at room temperature.

There are number of organomoselium compounds such as triethylmoselium, formed when moselium trihydride reacts with ethanol.

MsH3 + 3 C2H5OH → (C2H5)3Ms + 3 H2O

Occurrence and synthesis Edit

It is certain that moselium is virtually nonexistent on Earth, although in theory this element should exist primordially on Earth or as part of the decay chain of maxwellium or as beta decay product of democritium. This element can only be made naturally in tiny amounts by biggest supernovae or colliding neutron stars due to requirement of tremendous amount of energy. Additionally, this element can also be made artificially in much larger quantities by advanced technological civilizations, making artificial moselium more abundant than natural moselium in the universe. An estimated abundance of moselium in the universe by mass is 8.99 × 10−16, which amounts to 3.01 × 1037 kilograms.

To go along with other such civilizations, humans on Earth may eventually have the capability to synthesize moselium. To synthesize most stable isotopes of moselium, nuclei of a couple lighter elements must be fused together, and right amount of neutrons must be seeded. This operation would be very difficult since it requires a great deal of energy. Here's couple of example equations in the production of the most stable isotope 331Ms.
