Answer:
On emission of 2 alpha particles, mass number is reduced by 8 and atomic number by 4.
z S A → z−4 Q A−8 +2 2 He 4
Now, on emission of 1 beta particle, mass number remains same but atomic number increases by 1.
z−4
Q A−8 → z−8R A−8 + −10β
After decay, given element is
85
R 222 . Therefore,A−8=222⇒A=230
(Atomic Mass)
Z−3=85⇒Z=88
