"Three-center two-electron bonds " are seen in many boron compounds, such as diborane ( B 2 H 6 ).
12.
Two labs report that the magnesium-boron compound becomes " superconducting " at temperatures of around minus 388 degrees to minus 389 degrees.
13.
Small amounts of boron compounds play a strengthening role in the cell walls of all plants, making boron a necessary plant nutrient.
14.
However, despite its name, " Borateem " laundry bleach no longer contains any boron compounds, using sodium percarbonate instead as a bleaching agent.
15.
Estimated global consumption of boron ( almost entirely as boron compounds ) was about 4 million tonnes of B 2 O 3 in 2012.
16.
Under alkaline conditions, boron compounds such as boric acid or borax cause the polymer to cross-link, forming tackifying precipitates or toys such as Flubber.
17.
Several boron compounds, especially the oxides, have unique and valuable properties that have led to their substitution for other materials that are less useful.
18.
Some experts said the magnesium-boron compound might pay off in making very fast computer components, where the oxygen-containing materials have proven hard to work with.
19.
Note that scandium has many unique boron compounds, as shown in figure 2, because of the much smaller ionic radius compared with other rare-earth elements.
20.
As a formality, the lewis structures of many boron compounds have only six valence electrons around boron ( which is sometimes but not always accurate ).
