Boron (atomic symbol: B, atomic number: 5) is a Block P, Group 13, Period 2 element with an atomic weight of 10.81. The number of electrons in each of boron's shells is 2, 3 and its electron configuration is [He] 2s22p1. The boron atom has a radius of 90 pm and a Van der...
Boron is a metalloid established on the thirteen groups in the periodic table with atomic number 5, atomic mass 10.811 g/mol and chemical icon B. Even if boron complexes have been identified for many centuries, it had various types of isotopes; 10B and 11B are the utmost constant ones...
It provides atomic mass, mass excess, nuclear binding energy, nucleon separation energies, Q-values, and nucleon residual interaction parameters for atomic nuclei of the isotope B-10 (Boron, atomic number Z = 5, mass number A = 10). Landolt-Brnstein Homepage Introduction Index...
Boron has the atomic number 5 and the symbol B, and is a so-called metalloid. Boron compounds have been known for many centuries and especially used in the production of glass. At the beginning of the nineteenth century, it was recognised that boron is an essential micronutrient for plants....

It was found that elastic collisions decrease by up to 10% the boron KLL Auger electron signal. In addition, the sampling depth of AES was strongly decreased. This decrease reached 35% for medium atomic number elements. The values of parameters correcting for elastic scattering effects were ...
8–10 and Table S2), which is due to the much smaller radius of the substitutional boron dopant than the metallic atom. To study the impact of interstitial boron doping on the electronic properties of SnO2, ZnO, and In2O3 samples, Mott–Schottky analysis of impedance was conducted. ...
