Question

Thorium-231 is the product when a certain radioisotope emits alpha particle. Thorium-231 is radioactive and emits a beta particle. Write a nuclear equation for the reaction in which isotope is produced. Write a second reaction that shows the product of Thorium-231 decay. ...... ---> 231/90 Th + 4/2 alpha 231/90 Th -----> ....... + 0/-1 beta

Answer 1

In this kind of excercises is easier to think like a math equation, i will show you how:

Now let´s do the same with the second reaction:
