Protons/Electrons:56 Neutrons:81 Shell structure:2,8,18,18,8,2 Electron configuration:[Xe]6s2 Oxidation state:2 Crystal structure:cubic body centered Primary uses for barium are in fireworks, vacuum tubes, fluorescent lamps, and sparkplugs. Barium, meaning “heavy” from the Greek...
An excellent pulse shape discrimination between neutrons (protons) and γ-rays (electrons) has been obtained in BPS.doi:10.1016/0168-9002(88)90735-8S. KubotaT. MotobayashiJ. Ruan(Gen)T. MurakamiJ. KasagiElsevier B.V.Nuclear Instruments and Methods in Physics Research Section A Accelerators ...
Double-β-decay involves the simultaneous conversion of two neutrons into two protons, and the emission of two electrons and two neutrinos; the neutrinoless process, although not yet observed, is thought to involve the emission of the two electrons but no neutrinos. The search for neutrinoless-dou...

The number of valence electrons in an element with electron configuration 1s^22s^22p^63s^23p^4 is [{Blank}]. Determine the following information for barium. a. atomic number b. number of protons, neutrons, and electrons in ...
The atomic weight was calculated as the sum of the weight of all protons, neutrons and electrons present in the atom. The weight of the unit cell was calculated as: atomic weight multiplied by the number of atoms present in a unit cell. The density of the unit cell was computed as ...
