  2. Photodisintegration - Wikipedia

    en.wikipedia.org/wiki/Photodisintegration

    Photodisintegration is endothermic (energy absorbing) for atomic nuclei lighter than iron and sometimes exothermic (energy releasing) for atomic nuclei heavier than iron. Photodisintegration is responsible for the nucleosynthesis of at least some heavy, proton-rich elements via the p-process in supernovae of type Ib, Ic, or II. This causes the ...

    en.wikipedia.org/wiki/List_of_fictional_elements...

    [75] [76] This metal is stronger than other well-known fictional metals that also exist in the game, such as Mithril and Adamant. SAM Satisfactory: Glassy purple/indigo mineral able to manipulate atomic bonds of any matter within physical contact of it when "Reanimated". Used to transform materials, and to progress through alien technology ...

  4. Native metal - Wikipedia

    en.wikipedia.org/wiki/Native_metal

    [5] [6] Various amalgams of silver and mercury or other metals and mercury do occur rarely as minerals in nature. An example is the mineral eugenite (Ag 11 Hg 2) and related forms. [7] Silver nuggets, wires, and grains are relatively common, but there are also a large number of silver compound minerals owing to silver being more reactive than gold.

  5. Nuclear binding energy - Wikipedia

    en.wikipedia.org/wiki/Nuclear_binding_energy

    For lighter elements, the energy that can be released by assembling them from lighter elements decreases, and energy can be released when they fuse. This is true for nuclei lighter than iron/nickel. For heavier nuclei, more energy is needed to bind them, and that energy may be released by breaking them up into fragments (known as nuclear ...

  6. Ductile iron - Wikipedia

    en.wikipedia.org/wiki/Ductile_iron

    Much of the annual production of ductile iron is in the form of ductile iron pipe, used for water and sewer lines. It competes with polymeric materials such as PVC, HDPE, LDPE and polypropylene, which are all much lighter than steel or ductile iron; being softer and weaker, these require protection from physical damage.

  7. r-process - Wikipedia

    en.wikipedia.org/wiki/R-process

    In nuclear astrophysics, the rapid neutron-capture process, also known as the r-process, is a set of nuclear reactions that is responsible for the creation of approximately half of the atomic nuclei heavier than iron, the "heavy elements", with the other half produced by the p-process and s-process.

  8. Nonmetal - Wikipedia

    en.wikipedia.org/wiki/Nonmetal

    Physically, they are usually lighter (less dense) than elements that form metals and are often poor conductors of heat and electricity. Chemically, nonmetals have relatively high electronegativity or usually attract electrons in a chemical bond with another element, and their oxides tend to be acidic .

  9. Mithril - Wikipedia

    en.wikipedia.org/wiki/Mithril

    Mithril is a fictional metal found in J. R. R. Tolkien's Middle-earth writings. It is described as resembling silver, but being stronger and lighter than steel.It was used to make armour, such as the helmets of the citadel guard of Minas Tirith, and ithildin alloy, used to decorate gateways with writing visible only by starlight or moonlight.
