1.4 Nuclear Structure and Intro to Nuclear Chemistry Flashcards
1
Q
Stable nucleus (stability rules)
A
Stable Nucleus:
1) Even number of proton and neutrons
2) N/Z = 1 for elements up to Ca (20)
N/Z > 1 for elements past Ca (20)
2
Q
Nuclear R(x)
A
Parent —> daughter nuclei + energy
- a daughter is more stable, and is lighter in mass.
