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 Be-9 (Beryllium, atomic number Z = 4, mass number A = 9). Landolt-Brnstein Homepage Introduction Index...
Beryllium played a large part in proving the existence of neutrons. In 1932, James Chadwick, an English physicist, bombarded a sample of beryllium with alpha-rays (heliumnuclei). He observed that the bombarded sample emitted a subatomic particle, which had mass but no charge. This neutral parti...
The quantitative determination of beryllium, even in very small amounts, is especially important because of the toxicity of beryllium. The best method is atomic absorption spectrometry.When an acetylene/nitrous oxide flame is used, even beryllium oxide is excited, and it is possible to analyze any...
Beryllium has the electronic configuration [He] 2s2. In its chemistry beryllium exhibits the +2 oxidation state and the only evidence of lower valence of beryllium is in the solubility of the metal in BeCl2.[16] The small atomic radius ensures that the Be2+ ion would be highly polarizing le...
These quotients are then added, and the atomic percentage calculated by dividing each quotient by the sum times 100. For example, 77 wt% Ni 59 = 1.305, 21 wt% Cr ÷ 52 = 0.404, and 2 wt% Be ÷ 9 = 0.222. The sum of the quotients is 1.931, and 0.222 ÷ 1.931 × 100 = 11.5...

For bulk stoichiometric calculations, we are usually determining molar mass, which may also be called standard atomic weight or average atomic mass.Using the chemical formula of the compound and the periodic table of elements, we can add up the atomic weights and calculate molecular weight of the...
