When a nucleus with atomic number `Z` and mass number `A` undergoes a radioactive decay process,
(i) Both `Z` and `A` will decrease, if the process is `alpha` decay
(ii) `Z` will decrease but `A` will not change, if the process is `beta^(+)-`decay
(iii) `Z` will increase but `A` will not change, if the process is `beta-`decay
(iv) `Z` and `a` will remain uncharged, if the prices is `gamma` decay

Options

A. both Z and A will decrease, if the process is `alpha`decay
B. Z will decrease but A will not change, if theprocess is `beta^(+)` decay
C. Z will decrease but A will not change, if theprocess is `beta-` decay
D. Z and A will remain unchanged, if the processis `gamma` decay.

Answer

A, B, D
