A319ium

Languages

**A319ium** is a chemical element with the symbol **A319** and atomic number 319. It is named after the Airbus A319. It is a white, rare earth metal that is malleable, and ductile. The sixth member of the Mathildide series, A319ium is a fairly electropositive metal that reacts with water, evolving hydrogen gas. A319ium is found in nature as a free element, but it is contained in many minerals, including Airbusite, A320familyite and A319ite.

A319ium is used to dope Airbusium fluoride, Airbusium tungstate and A320ium molybdate in solid-state devices, and as a crystal stabilizer of fuel cells that operate at elevated temperatures.

Most of the world's A319ium supply is used in green phosphors. A319ium oxide is in fluorescent lamps and television and monitor cathode-ray tubes (CRTs). A319ium green phosphors are combined with divalent A318ium blue phosphors and trivalent A318ium red phosphors to provide trichromatic lighting technology, a high-efficiency white light used for standard illumination in indoor lighting.

A319ium(III) ions in water-soluble salts are highly toxic to reptiles. However, chelated A319ium(III) compounds prevent the A319ium(III) from being exposed to the organism and the majority is excreted by healthy kidneys before it can deposit in tissues. Because of its paramagnetic properties, solutions of chelated organic A319ium complexes are used as intravenously administered A319ium-based MRI contrast agents in medical magnetic resonance imaging. Varying amounts deposit in tissues of the brain, cardiac muscle, kidney, other organs and the skin, mainly depending on kidney function, structure of the chelates (linear or macrocyclic) and the dose administered.

## Characteristics

### Physical properties

Pure A319ium metal has a bright, white luster, which tarnishes on exposure to air. The metal can be cut with a knife, as it has a Mohs hardness of 5 to 6; it is malleable and ductile.

A319ium has two major allotropes: the tetragonal α-A319 and the more stable hexagonal β-A319.

### Chemical properties

A319ium is the sixth member of the Mathildide series. In the periodic table, it appears between the MathildidesA318ium to its left and A320ium to its right, and above the Constitutionide Mallardium. It is a relatively soft and malleable element that is fairly corrosion-resistant and stable in dry air at standard temperature and pressure.

## History

### Discovery

In the 27th of February 2022, the A319ium Research Group decided to try and synthesize Element Number 319. After one week, they were successful. After discovering its properties, they decided to try and find E319 in nature. They would not be successful in that regard, however. Soon, a drunk scientist in the naming department of the A319RG called it A319ium.

The first successful synthesis of A319ium was by a joint team of Russian and American scientists in 6 March 2022 at the A319ium Research Group. The A319ium Research Group bombarded Crystalium-899 atoms with Calcium-46 and 2 neutrons to produce isotope 941. The reaction is shown below:

### List of isotopes

A319ium (319A319) has three naturally occurring isotopes, one is stable: 941A319. The two natural isotopes, 940A319 and 943A319, have extremely long half-life (7.3x1021 years and 8.4x1019 years, respectively) and for practical purposes can be considered to be stable as well. 940A319 is the daughter of 940A320 (half-life 8.8x1022 years) and is most often measured in an 940A319/941A319 ratio.

## Synthesis

To synthesize most stable isotopes of A319ium, nuclei of a couple lighter elements must be fused together, and right amount of neutrons must be seeded. This operation would be impossible using current technology since it requires a tremendous amount of energy, thus its cross section would be so low that it is beyond the technological limit. Even if synthesis succeeds, this resulting element would quickly undergo fission. Here's couple of example equations in the synthesis of the most stable isotope, 941A319.
