Review Constants | Periodic Tat When a 99 U nucleus is bombarded by neutrons (n) it undergoes a fission feaction, resulting in the formation of two new nuclei and neutrons. The following equation is an example of one such fission process: U + n-Ba + Kr + 3on Enter the isotope symbol for the barium (Ba) nucleus in this reaction. Express your answer as an isotope.

Beryllium-8 is an unstable isotope and decays into two α particles, which are helium nuclei with mass 6.68×10−27kg. This decay process releases 1.5×10−14J of energy. For this problem, let's assume that the mass of the Beryllium-8 nucleus is just twice the mass of an α particle and that all the energy released in the decay becomes kinetic energy of the α particles. If the Beryllium-8 nucleus is moving in the positive x-direction with a speed of 1.0×106 m/s when it...

What happens when certain elementary particles (such as electrons or neutrons) are missing or are over-abundant and how do atoms build stable structures such as molecules and crystals.
1) Answer the questions about the 2-hexanone. a) When bombarded with electrons in EIMS, what is the most likely (most stable) radical cation that is formed? b) From this radical cation, two alpha cleavage reactions are likely. Draw the mechanism of both and predict the fragments c) In addition to alpha cleavage, this molecule can also undergo a McLafferty rearrangement mechanism to predict the fragments . Drawa
