Question

When Uranium – 235 absorbs a slow-moving neutron, it splits into Iodine (atomic number 53 and mass number 130), a second element, and two neutrons. What is the second element? Must give symbol, atomic number, and mass number.?

Answer 1

When Uranium-235 (U-235) absorbs a slow-moving neutron and undergoes fission, it can split into different products. One possible outcome is the formation of Iodine-131 (I-131), a second element, and two additional neutrons.

The second element in this fission reaction would be Xenon, which has the atomic number 54. The specific isotope of Xenon produced in this reaction is Xenon-133 (Xe-133).

To summarize:

• Symbol of the second element: Xe
• Atomic number of the second element: 54
• Mass number of the second element: 133

So, the second element is Xenon-133 (Xe-133).
