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 Se-108 (Selenium, atomic number Z = 34, mass number A = 108)....
Selenium (pronounced /sɨˈliːniəm/ sə-LEE-nee-əm) is a chemical element with the atomic number 34, represented by the chemical symbol Se, an atomic mass of 78.96. It is a nonmetal, chemically related to sulfur and tellurium, and rarely occurs in its elemental state in n...
Selenium is a nonmetal trace element with atomic number 34 and atomic mass of 78.96. It is mostly found in nature as inorganic selenite, or organic amino acids selenomethionine and selenocysteine. Selenocysteine is present in the catalytic sites of selenoproteins. Humans have 25 selenoproteins. Most...
The Selenium , with the cas number 7782-49-2, a chemical element with the atomic number 34, and, also exists in many non-conductive forms: a black glass-like allotrope, as well as several red crystalline forms built of eight-membered ring molecules. It is found in economic quantities in...
