Schrodium is the fabricated name of a hypothetical element with the symbol So and atomic number 150. Schrodium was named in honor of Erwin Schrödinger (1887–1961), who developed his equation for quantum mechanics. This element is known in the scientific literature as unpentnilium (Upn), eka-californium, or simply element 150. Schrodium is the tenth member of the dumaside series, found in the third row of f-block (below dysprosium and californium); this element is located in the periodic table coordinate 6f10.
Schrodium, even as a metal, is not gray, white, gold, reddish, nor bluish, but green. The metal appears green because electrons exchange energies at frequencies that would put at green region of the spectrum at around 525 nanometers.
Its density is 9.56 g/cm3, which is about average for a metal. One mole of schrodium weighs 422.5 grams or about 15 ounces. The sound travels through thin rod of metal at 4582 m/s, little above average for an element. Schrodium has a hexagonal crystal lattice, formed when atoms arrange together to form unique shapes. One cubic centimeter of schrodium contains 13.6 sextillion atoms, and separated by an average of 419 pm (4.19 Å) apart.
Schrodium's phase points are much lower than neighboring elements due to closed orbitals and split orbitals including 6f5/2 suborbital. It melts at 835°R (191°C) and boils at 1652°R (645°C). However, melting and boiling points are not the same at every condition as pressure is the variable. Melting and boiling points given here are from Earth's atmospheric pressure at sea level, 101.325 kPa or 1 atm, which is the default pressure when determining phase points of elements, compounds, and mixtures. If we put schrodium in low pressure environment, both phase points would be lower, but boiling point would decrease far more rapidly with the same amount of decrease in pressure. Because of this, boiling point would catch up to the melting point, and when both phase points are identical in temperature, it is called a triple point. For schrodium, triple point is at a pressure of 2.24 kPa, 1⁄45 the Earth's sea level pressure. In conclusion, if we decrease pressure applied on schrodium 45 times, from default pressure to triple point pressure, boiling point would lower by 816.58°R (453.87°C), but its melting point would lower by only 0.39°R (0.22°C). If we increase the ambient pressure around schrodium from default pressure by 6309 times, it would exist as supercritical fluid beyond its boiling point. At 6309 atmospheres, its boiling point would be 8810°R (4621°C), while its melting point would be 838°R (192°C). Its liquid range would be 7972°R (4429°C) and its liquid ratio would be 10.52, compared to 817°R (454°C) and 1.98, respectively at default pressure.
Schrodium atom is comprised of 569 subatomic particles, 419 of these make up the nucleus (protons and neutrons), while the remaining 150 are found surrounding the nucleus (electrons). The atomic mass is 422.5 daltons, twice as heavy as astatine atom; its radius is 129 picometers, similar in size to copper atom.
Schrodium has meta states, which are excited states of isotopes. The longest lived meta state has a half-life of 380 milliseconds for 420m1So, 1⁄15 the half-life of 419So.
Schrodium is lot less reactive than californium because electrons between 8s and 8p1/2 orbitals are bound, resulting in higher ionization energies, thus making it hard to form compounds. The common oxidation states for schrodium are +1 (monovalent) and +2 (divalent), compared to +3 (trivalent) for californium. In aqueous solutions, So2+ (dark blue) is more stable than So+ (green).
Schrodium compounds are rare since it is so unreactive. Still, schrodium can form halides since halogens are the most reactive group of elements that can combine with metals. Examples of halides are schrodium monofluoride (SoF), schrodium difluoride (SoF2), monochloride (SoCl), and dichloride (SoCl2). Schrodium can possibly form other compounds, such as So2O, SoO, So2CO3, and So3PO4.
Schrodium can react with carbon, along with hydrogen, oxygen, and/or others to form organic compounds involving schrodium, called organoschrodium. One example is dimethylschrodium (So(CH3)2), a colorless liquid with a freezing point of 473°R (−10°C) and boiling point of 826°R (186°C).
Occurrence and synthesis Edit
It is almost certain that schrodium doesn't exist on Earth at all, but it is believe to exist somewhere in the universe, at least barely. Since every element heavier than lithium were produced by stars, then schrodium must be produced in stars, and then thrown out into space by exploding stars. But it is theoretically impossible for even the most powerful supernovae or most violent neutron star collisions to produce this element through r-process because there's not enough energy available or not enough neutrons, respectively, to produce this hyperheavy element. Instead, this element virtually can only be made by advanced technological civilizations. An estimated abundance of schrodium in the universe by mass is 9.10 × 10−36, which amounts to 3.05 × 1017 kilograms or twice the mass of Saturn's moon Promethius worth of schrodium.
To go along with other such civilizations, humans on Earth may eventually have the capability to synthesize schrodium. To synthesize most stable isotopes of schrodium, nuclei of a couple lighter elements must be fused together, and right amount of neutrons must be seeded. This operation would be extremely difficult since it requires a vast amount of energy and even if nuclei of this element were produced would quickly decay due to its short half-life. Here's couple of example equations in the production of the most stable isotope, 419So.
