Boron (Properties, Occurrence, Uses) Assignment Point

Boron (B) is a non-metallic element of group 13 (IIIa, or boron group) and is the only non-metallic element of the periodic table of elements. With the symbol B and the atomic number 5, it is a chemical element. It is a low-abundance element in the Solar System and in the Earth's crust, formed entirely by cosmic ray spallation and supernovae and not by stellar nucleosynthesis.

Organoboron chemistry Wikipedia

Properties of the B-C bond. The C-B bond has low polarity (the difference in electronegativity 2.55 for carbon and 2.04 for boron), and therefore alkyl boron compounds are in general stable though easily oxidized.. In part because its lower electronegativity, boron often forms electron-deficient compounds, such as the triorganoboranes. Vinyl groups and aryl groups donate electrons and make

Ionization energy Wikipedia

Ionization energy is also a periodic trend within the periodic table. Moving left to right within a period, or upward within a group, the first ionization energy generally increases, with exceptions such as aluminium and sulfur in the table above. As the nuclear charge of the nucleus increases across the period, the electron shielding remains constant, hence the atomic radius decreases, and
