Problem # 42Radioactivity Exercises[Solved]

Exercises: Complete the following nuclear equations:

1/ 22990Th →   22588Ra +  ?

2/ 10n   →   11p  +  ?

3/ 21684Po   →  0-1e  + ?

4/ 23592U  +  10n (bombardment by neutron)  →  14456Ba  + ?  +  210n

5/ ?   →  23490Th  + α

6/ 23491Pa  →  ? +  β

Solutions

1-      22990Th  →  22588Ra + 42α alpha emission (42He)

2-      10n  → 11p  +  0-1e  beta emission (β) by transforming a neutron into a proton

3-      21684Po  →  0-1e  +  21685At

4-      23592U  +  10n  →  14456Ba  +  8936Kr  +  210n   nuclear fission by neutron bombardment

5-      23892U  →  23490Th  +  α (42He)

6-      23491Pa  →  23492U  +  β (0-1e)
