Answer :
Final answer:
The product of the alpha decay of cesium-137 is barium-133. The alpha decay process reduces the atomic number of cesium, resulting in the formation of barium. While your options mention barium-131, the correct isotope is actually barium-133.
Explanation:
Alpha Decay of Cesium-137
When cesium-137 (¹³⁷Cs) undergoes alpha decay, it emits an alpha particle (which consists of 2 protons and 2 neutrons) and transforms into a different element. Since alpha decay decreases the atomic number of the original nucleus by 2, the daughter nuclide formed is barium-133 (¹³³Ba), which has the atomic number 56. The equation representing this decay is as follows:
¹³⁷Cs → ¹³³Ba + α
Therefore, out of the options provided:
- Olodine-133
- Barium-131
- Neodymium-141
- Olodine-141
the correct product of the alpha decay of cesium-137 is Barium-133, as it has the right atomic number and mass number. Note that there is a naming error in your options; the correct daughter product after alpha decay is barium-133, not barium-131.
