Green liquid with symbol Ar and atomic number 7. Makes a compound that is corrosive to copper when mixed with Galine and Sanite, and a compound that produces clouds when exposed to air when mixed with Regalite. The real element 7 is nitrogen; and Ar = argon. Atium Mistborn: Metal. Forms the body and power of the shard Ruin. If an Allomancer ...
Volcanic ash plumes can form above pyroclastic density currents. These are called co-ignimbrite plumes. As pyroclastic density currents travel away from the volcano, smaller particles are removed from the flow by elutriation and form a less dense zone overlying the main flow. This zone then entrains the surrounding air and a buoyant co ...
Hume-Rothery rules, named after William Hume-Rothery, are a set of basic rules that describe the conditions under which an element could dissolve in a metal, forming a solid solution. There are two sets of rules; one refers to substitutional solid solutions, and the other refers to interstitial solid solutions.
Compounds of Ga(II) would have an unpaired electron and would behave as a free radical and generally be destroyed rapidly, but some stable radicals of Ga(II) are known. [36] Gallium also has a formal oxidation state of +2 in dimeric compounds, such as [Ga 2 Cl 6] 2−, which contain a Ga-Ga bond formed from the unpaired electron on each Ga atom ...
The term "Janus Particle" was coined by author Leonard Wibberley in his 1962 novel The Mouse on the Moon as a science-fictional device for space travel.. The term was first used in a real-world scientific context by C. Casagrande et al. in 1988 [8] to describe spherical glass particles with one of the hemispheres hydrophilic and the other hydrophobic.
Plutonium in the δ (delta) form normally exists in the 310 °C to 452 °C range but is stable at room temperature when alloyed with a small percentage of gallium, aluminium, or cerium, enhancing workability and allowing it to be welded. [19] The δ form has more typical metallic character, and is roughly as strong and malleable as aluminium. [17]
Organolithium compounds are electrically non-conducting volatile solids or liquids that melt at low temperatures, and tend to form oligomers with the structure (RLi) x where R is the organic group. As the electropositive nature of lithium puts most of the charge density of the bond on the carbon atom, effectively creating a carbanion ...
Antimony trioxide is formed when antimony is burnt in air. [25] In the gas phase, the molecule of the compound is Sb 4 O 6, but it polymerizes upon condensing. [12] Antimony pentoxide (Sb 4 O 10) can be formed only by oxidation with concentrated nitric acid. [26] Antimony also forms a mixed-valence oxide, antimony tetroxide (Sb 2 O
