Nuclear Chemistry Flashcards
U-238 Decays via Alpha decay to Th-234. What is the Equation?
What happens in Beta Minus Decay?
N –> P+ Beta -
Neutron turns to a proton and a beta minus particle
C-14 decays via beta minus to N-14 what is the Equation?
Derive the First Order Reaction Equation that mimics decay.
Describe what the Unit Bq means
1 Disintegration per second
Describe what the unit Ci means
3.7X10^10 Disintegrations per second
Derive the Equation for calculating a half life
What is a Half Life?
What happens in Beta plus Decay?
p —> N + Beta+
Protons turns into a neutron and a beta plus particle aka Positron
If an isotope is below the stability line would it tend to undergo Beta Plus , Beta Minus or Alpha
Beta Minus
if an isotope is above the stability line would it tend to undergo Beta Plus , Beta Minus or Alpha
Beta Plus
if an isotope is above Z=82 would it tend to undergo Beta Plus , Beta Minus or Alpha
alpha
What is the Method to find binding energy
Find the Mass Defect in U
( Mass of Individual components - measured mass)
Convert U To energy using E=MC^2
Explain why Fission and fusion occur.
Most stable atom is Iron Fe-56
If Atomic Number is below 26- atoms will undergo fusion to try to get up to 26 protons
If Atomic Number is above 26- atoms will undergo fission to try to get down to 26 protons
What is Transmutation
Conversion of a nucleus to another via natural or externally stimulated decay
What is Fission
Heavy nuclei splits into lighter daughter nuclei
What is Fusion
Light Nucleu merge into a heavier nucleus
