equation of nuclear fission of urnaium 235 forming iodine 131
Assume the fission products include three neutrons and Y-102.
The number of protons and neutrons before and after the reaction will agree, as required. Yttrium (Y) has atomic number 39. Iodine's is 55. That adds up to 92, the atomic number of U.
Put that all together in a reaction.
Iodine's atomic number is 53. The rest of the answer is OK as written
The nuclear fission of uranium-235 (U-235) that forms iodine-131 (I-131) can be represented by the following equation:
U-235 + neutron -> I-131 + X + 2-3 neutrons
In this equation, a U-235 atom absorbs a neutron (symbolized as "neutron") and undergoes fission, resulting in the formation of I-131 and some other products denoted by "X." Additionally, 2 to 3 neutrons are released as byproducts of the fission process.
The equation for nuclear fission of uranium-235 (U-235) forming iodine-131 (I-131) can be expressed as follows:
U-235 + neutron -> Ba-141 + Kr-92 + 3 neutrons + energy
To understand how to arrive at this equation, let's break it down step by step:
1. Nuclear fission occurs when the nucleus of an atom is split into smaller fragments. In the case of U-235, it can undergo fission when it absorbs a neutron.
2. When a U-235 nucleus absorbs a neutron, it becomes highly unstable. This causes it to split into two smaller atoms called fission fragments.
3. In this specific fission process, one of the fission fragments is barium-141 (Ba-141). The other fragment is krypton-92 (Kr-92). These two isotopes are formed due to the splitting of the U-235 nucleus.
4. Along with the fission fragments, three additional neutrons are released as byproducts. These neutrons can then go on to induce the fission of other U-235 nuclei in a chain reaction, releasing more energy.
5. Finally, a significant amount of energy is released during the fission process, which is a characteristic feature of nuclear reactions.
It's worth noting that the equation represents a specific instance of U-235 fission, and variations can occur depending on the conditions of the reaction. However, the basic principle of fission splitting the U-235 nucleus into smaller fragments remains the same.
