Options:
A) Two a-particles and one b-particle
B) Three $ {{\beta }^{+}} $ particles
C) One a particle and two $ {{\beta }^{+}} $ particles
D) One a particle and two $ {{\beta }^{-}} $ particles
Show Answer
Answer:
Correct Answer: A
Solution:
By using $ {n_{\alpha }}=\frac{A-{A}’}{4} $ and $ {n_{\beta }}=2{n_{\alpha }}-Z+Z’ $
BETA
