In a radioactive decay chain reaction, 230 /90 Th nucleus decays into

Question

In a radioactive decay chain reaction, \(\underset{90}{230}\) Th nucleus decays into \(\underset{84}{214}\) po nucleus. The ratio of the number of α to number of β^- particles emitted in this process is______.

Answer 1

(from consv. Of mass no and charge)

So \(\frac{n_\alpha}{n_\beta}=\frac{4}{2}=2\)
