Reactions ((new)): 4.2.1 Project Modeling Nuclear

| Reaction Type | Description | Example | |---------------|-------------|---------| | | Nucleus emits an alpha particle (2 protons, 2 neutrons) | Uranium-238 → Thorium-234 + Helium-4 | | Beta Decay | Neutron turns into proton + electron (beta particle) | Carbon-14 → Nitrogen-14 + electron | | Gamma Decay | Nucleus releases energy (gamma ray), no change in particles | Cobalt-60 → Cobalt-60 + γ | | Nuclear Fission | Heavy nucleus splits into smaller nuclei + neutrons + energy | Uranium-235 + neutron → Barium-141 + Krypton-92 + 3 neutrons | | Nuclear Fusion | Light nuclei combine into heavier nucleus + energy | Hydrogen-2 + Hydrogen-3 → Helium-4 + neutron |

Write balanced nuclear equations for your reaction. Example (fission of U-235): [ \text^235 92U + \text^1 0n \rightarrow \text^141 56Ba + \text^92 36Kr + 3\text^1_0n + \textenergy ] 4.2.1 project modeling nuclear reactions

Requires extreme heat and pressure to overcome electrical repulsion. Produces highly radioactive fission products. Produces little to no long-term radioactive waste. Evaluating and Creating Models | Reaction Type | Description | Example |
