Question

How many groups of nuclei are generated in fission of 235 U? What are their characteristics? PLs answer it's urgent

Answer 1

Its nucleus breaks into two fragments "nuclei" each containing an equal mass.

Explanation:

• In a nuclear fission reaction, a large amount of energy is produced.
• Radioactive decay of the element continues even after the fission reaction has stopped.
• In a fission reaction, a neutron is captured by U-235 and it becomes unstable.
• Its nucleus breaks into two fragments each containing an equal mass.
• These fragments of nuclei then further proceed with the reaction and several combinations are possible.

Answer 2

Nuclear Reactors

Explanation:

When uranium-235 is irradiated with neutrons, the uranium atoms split through a process called fission, releasing more neutrons, atoms with smaller atomic numbers, and large amounts of heat. The heat is harnessed to create electricity, similar to conventional fossil fuel power plants. Nuclear reactors use material called fissile material as fuel. These are material which will undergo fission reaction easily when bombarded by neutrons. The two most frequently used fuel are Uranium-235 and Plutonium-239.
