Question

The answer is B. I am not sure how to arrive at this answer.

The stability of^11 _6 with respect to alpha, beta- plus and beta- minus decay is to be determined. The following atomic masses are known:^4 _2 He: 4.002603 u^7 _4 Be 7.016928 u^11 _ 5 B: 11.009305 u^11 _6 C: 11.011433 u^11 _7 N: 11.026742 u The^11 _6 C nucleus is A) subject to alpha decay only. B) subject to beta- plus decay only. C) subject to beta- plus or beta- minus decay, but not to alpha decay. D) not subject to alpha, beta- plus or beta- minus decay. E) subject to beta-minus decay only.

Explanation / Answer

Because by doing so it achieves the stable configuration of 11B5 , you should know that in beta + decay the positrons are released thus subtracting one atomic no.
