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)
