If  23392U decays twice by ∝-emission. what is the resulting isotope?
(Ans : 
 22588Rn )



Given Data:


Element =  23392U

∝-emission (twice)



To Find:


Resulting Isotopes = ?



Solution:

The general reaction for ∝-emission is

 AZX  →   A-4Z-2X +  42 + Energy

According to the given conditions, the reaction will be as follows (After 1st ∝-emission)

 23392U   →   22990Th +  42 + Energy  

After 2nd ∝-emission

 22990Th   →   22588Rn +  42 + Energy  


Thus the remaining isotopes are 

 22588Rn ----------------Ans
