Among W 74 160 and W 74 185 we have to find which isotope decays by alpha decay and which decays through beta decay. Concept Introduction: Atoms with unstable nuclei are constantly changing as a result of the imbalance of energy within the nucleus. They constantly try to come to a stable state. This is possible when the nuclei of unstable isotopes spontaneously disintegrate, or transform, in a process known as radioactive decay. Alpha emission = In an alpha emission the mass number reduces by 4 and the atomic number reduces by 2 of the product nucleus. Alpha particle is generally denoted by H 2 4 e . Beta emission = Beta decay is a process in which a nuclei emits a particle which has 0 mass but charge of an electron from it. So the mass number remains the same however the atomic number reduces by 1 for the new nucleus.

Interpretation:

Among W74160 and W74185 we have to find which isotope decays by alpha decay and which decays through beta decay.

Concept Introduction:
Atoms with unstable nuclei are constantly changing as a result of the imbalance of energy within the nucleus. They constantly try to come to a stable state. This is possible when the nuclei of unstable isotopes spontaneously disintegrate, or transform, in a process known as radioactive decay.
Alpha emission = In an alpha emission the mass number reduces by 4 and the atomic number reduces by 2 of the product nucleus. Alpha particle is generally denoted by H24e.
Beta emission = Beta decay is a process in which a nuclei emits a particle which has 0 mass but charge of an electron from it. So the mass number remains the same however the atomic number reduces by 1 for the new nucleus.

Give the product of the bimolecular elimination from each of the isomeric halogenated compounds. Reaction A Reaction B. КОВ CH₂ HotBu +B+ ко HOIBU +Br+ Templates More QQQ Select Cv Templates More Cras QQQ One of these compounds undergoes elimination 50x faster than the other. Which one and why? Reaction A because the conformation needed for elimination places the phenyl groups and to each other Reaction A because the conformation needed for elimination places the phenyl groups gauche to each other. ◇ Reaction B because the conformation needed for elimination places the phenyl groups gach to each other. Reaction B because the conformation needed for elimination places the phenyl groups anti to each other.
