Question 1

The stability of Cl with respect to alpha, beta-plus and beta-minus decay is to be determined. The following atomic masses are known:
He:4.002603 u
P:31.973907 u
S:35.967081 u
Cl:35.968307 u
Ar:35.967546 u
The Cl nucleus is
◦ subject to alpha decay only.
◦ not subject to alpha, beta-plus or beta-minus decay.
◦ subject to beta-plus decay only.
◦ subject to beta-plus or beta-minus decay, but not to alpha decay.
◦ subject to beta-minus decay only.

Question 2

Bismuth Bi is known to be radioactive. The stability of Bi with respect to alpha, beta-plus and beta-minus decay is to be determined. The following atomic masses are known:
He:4.002603 u
Tl:207.981998 u
Pb:211.991871 u
Bi:211.991255 u
Po:211.988842 u
The Bi nucleus is
◦ subject to beta-minus decay only.
◦ subject to beta-plus decay only.
◦ subject to alpha or beta-minus decay, but not beta-plus decay.
◦ subject to alpha decay only.
◦ subject to alpha or beta-plus decay, but not beta-minus decay.
