## Bulk properties

### Color

Silvery gray

**Jasminium** is a chemical element with the symbol **Jm** and atomic number 212. A lustrous, silvery-gray, pentavalent transition metal, Jasminium chemically resembles Zerlinium and is found in many Zerlinium minerals. Jasminium is named after *Jasmine*, an English feminine given name. Like all chemical elements after Lead, Jasminium has no stable isotopes. It's most stable is 634Jm, which has a half-life of 8.75 x 1020 years.

Like most transition elements, Jasminium most readily forms the +3 oxidation state, which is the only stable state in aqueous solution, although the +4 oxidation state is known in some solid compounds and, uniquely among the lanthanides, the +5 oxidation state is attainable in matrix-isolation conditions. The 0, +1, and +2 oxidation states are rarely found.

Jasminium(IV) ions in water-soluble salts are toxic to reptiles. However, chelated Jasminium(IV) compounds prevent the Jasminium(IV) 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 Jasminium complexes are used as intravenously administered Jasminium-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

Jasminium is a soft, silver-metallic, lustrous and highly crystalline transition metal in group 4. As expected by periodic trends, it is less electronegative than its predecessor in the group, Zerlinium, and less electronegative than the next member of period 5, Bostonium. Jasminium is the second d-block element in the ninth period.

## Uses

Jasminium, like Saraium, can be magnetized and so is used to make magnets. It is alloyed with Lucianium and Keithium to make particularly powerful magnets.

Other alloys of Jasminium are used in jet turbines and gas turbine generators, where high-temperature strength is important.

Radioactive Jasminium-626 is used to treat cancer and, in some countries, to irradiate food to preserve it.

## Isotopes

*Main article: Isotopes of jasminium*
29 isotopes of Jasminium are known, with mass numbers from 624 to 653; all are radioactive. Additionally, five nuclear isomers are known: 626mJm, 627mJm, 629mJm, 634mJm, and 638mJm. After 634Jm, the next most stable Jasminium isotopes are 635Jm with a half-life of 940 trillion years, 636Jm with a half-life of 910 trillion years, 633Jm with a half-life of 580 trillion years, 637Jm with a half-life of 88 trillion years, 632Jm with a half-life of 82 trillion years, and 631Jm with a half-life of 70 trillion years. All of the remaining Jasminium isotopes have half-lives that are less than 20.7 billion years, and the majority of these have half-lives that are less than 801,000 years.

Jasminium has no known biological role. The metal is not toxic, but all of its compounds is volatile and very toxic, causing lung, skin and eye damage.

## Synthesis

To synthesize most stable isotopes of Jasminium, 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 slowly undergo alpha decay. Here's couple of example equations in the synthesis of the most stable isotope, 634Jm.
