  2. Boron - Wikipedia

    en.wikipedia.org/wiki/Boron

    Boron is a component of neodymium magnets (Nd 2 Fe 14 B), which are among the strongest type of permanent magnet. These magnets are found in a variety of electromechanical and electronic devices, such as magnetic resonance imaging (MRI) medical imaging systems, in compact and relatively small motors and actuators.

  3. Electron configurations of the elements (data page) - Wikipedia

    en.wikipedia.org/wiki/Electron_configurations_of...

    Electron configurations of the elements (data page) This page shows the electron configurations of the neutral gaseous atoms in their ground states. For each atom the subshells are given first in concise form, then with all subshells written out, followed by the number of electrons per shell. For phosphorus (element 15) as an example, the ...

  4. Boron group - Wikipedia

    en.wikipedia.org/wiki/Boron_group

    The boron group is notable for trends in the electron configuration, as shown above, and in some of its elements' characteristics. Boron differs from the other group members in its hardness, refractivity and reluctance to participate in metallic bonding. An example of a trend in reactivity is boron's tendency to form reactive compounds with ...

  5. Periodic table (electron configurations) - Wikipedia

    en.wikipedia.org/wiki/Periodic_table_(electron...

    Periodic table (electron configurations) Configurations of elements 109 and above are not available. Predictions from reliable sources have been used for these elements. Grayed out electron numbers indicate subshells filled to their maximum. Bracketed noble gas symbols on the left represent inner configurations that are the same in each period.

  6. Boron compounds - Wikipedia

    en.wikipedia.org/wiki/Boron_compounds

    Boranes are chemical compounds of boron and hydrogen, with the generic formula of B x H y. These compounds do not occur in nature. Many of the boranes readily oxidise on contact with air, some violently. The parent member BH 3 is called borane, but it is known only in the gaseous state, and dimerises to form diborane, B 2 H 6.

  7. Three-center two-electron bond - Wikipedia

    en.wikipedia.org/wiki/Three-center_two-electron_bond

    A three-center two-electron (3c–2e) bond is an electron-deficient chemical bond where three atoms share two electrons. The combination of three atomic orbitals form three molecular orbitals: one bonding, one non -bonding, and one anti -bonding. The two electrons go into the bonding orbital, resulting in a net bonding effect and constituting a ...

  8. Boron nitride - Wikipedia

    en.wikipedia.org/wiki/Boron_nitride

    Boron nitride nanomesh. Boron nitride nanomesh is a nanostructured two-dimensional material. It consists of a single BN layer, which forms by self-assembly a highly regular mesh after high-temperature exposure of a clean rhodium [80] or ruthenium [81] surface to borazine under ultra-high vacuum.

  9. Boron monohydride - Wikipedia

    en.wikipedia.org/wiki/Boron_monohydride

    Borane (1), boron monohydride, hydridoboron or borylene is the molecule with the formula BH. It exists as a gas but rapidly degrades when condensed. By contrast, the cluster B 12 H 122- (dodecaborate), which has very similar empirical formula, forms robust salts.
