Such elements are predicted in the real world as an "Island of stability". In the novel by Jack Vance, duodecimates were deposited on a planet, Dar Sai, by the explosion of a nearby star. The planet's economy comes to depend on mining and sale of duodecimate ores. It is not revealed what the substance is actually used for. Duranium: Star Trek
The nondiagonal numbers say how many of the column's element occur in or at the row's element. [9] For example, the 2 in the first column of the second row indicates that there are 2 vertices in (i.e., at the extremes of) each edge; the 4 in the second column of the first row indicates that 4 edges meet at each vertex.
Materials science in science fiction is the study of how materials science is portrayed in works of science fiction.The accuracy of the materials science portrayed spans a wide range – sometimes it is an extrapolation of existing technology, sometimes it is a physically realistic portrayal of a far-out technology, and sometimes it is simply a plot device that looks scientific, but has no ...
The properties of any particular example of unobtainium depend on the intended use. For example, a pulley made of unobtainium might be massless and frictionless. But for a nuclear rocket , unobtainium might have the needed qualities of lightness, strength at high temperatures, and resistance to radiation damage; a combination of all three ...
Mesklin is a fictional planet created by Hal Clement and used in a number of his hard science fiction stories, starting with Mission of Gravity (1954). Alongside the novel's original 1953 serialization in Astounding Science Fiction, Clement published an essay titled "Whirligig World" detailing the process of designing the planet to have the properties he wanted.

A chemical element, often simply called an element, is a type of atom which has a specific number of protons in its atomic nucleus (i.e., a specific atomic number, or Z). [ 1 ] The definitive visualisation of all 118 elements is the periodic table of the elements , whose history along the principles of the periodic law was one of the founding ...
This is a list of chemical elements and their atomic properties, ordered by atomic number (Z).. Since valence electrons are not clearly defined for the d-block and f-block elements, there not being a clear point at which further ionisation becomes unprofitable, a purely formal definition as number of electrons in the outermost shell has been used.
