Nuclear fission - Study guides, Class notes & Summaries

CEM 141 MSU Exam 3 Latest Update Graded A+ Ionization Energy energy required to remove an electron from an atom in the gas phase Left Side Electrons have weaker attractions to remove electrons *easier to remove electrons from the left side of the table than the right side* Does it take MORE or LESS energy to remove an electron from Li than from Na? MORE Why? Because as we move down a group, the orbitals become larger and weaker. While going across the effective nuclear charge in...

APES AP Exam Review (2023/2024) 100% Pass First Law of Thermodynamics energy is neither created nor destroyed, may be converted from one form to another. Second Law of Thermodynamics when energy is changed from one form to another, some useful energy is degraded into lower quality energy (usually heat). Energy the ability to do work. Units of energy: joules, calories, kilocalories, British thermal units (BTUs), Kilowatt-hours (kWh) Power the rate of doing work (work/time). Units of power: wat...

EPRI - Reactor Theory Exam Questions and answers with 100% Complete Solutions | verified &updated 2024 Fission - A neutron interaction in which a nucleus absorbs a neutron, splits into two new nuclei and releases a large amount of energy; the resulting fission fragments emit neutrons and gamma rays and then undergo radioactive decay Turbines - A device with rotating blades that are connected to a shaft and turned by having a fluid do work on the blades; in a nuclear power plant, steam turbines...
