Uranium `""_(92)U^(238)` is not suitable for chain reaction . Why ?

Text Solution

AI Generated Solution

To understand why Uranium-238 (U-238) is not suitable for a chain reaction, we need to analyze its properties in comparison to other isotopes of uranium, particularly Uranium-235 (U-235), which is known to sustain a chain reaction. Here’s a step-by-step explanation: ### Step 1: Identify the Isotopes of Uranium Natural uranium consists of three isotopes: - Uranium-233 (U-233) - Uranium-235 (U-235) - Uranium-238 (U-238) ...
