1.	`_ (13)^(27) Al` is a stable isotope. `_(13)^(29) Al` is expected to disintegrated byA. `alpha` emissionB. `_(-1)^(0) beta` emissionC. Positron emissionD. Proton emission
Answer» Correct Answer - B Since `._(13)^(27) Al` is stable isotope , `._(13)^(29)Al` has `(n)/(P)` ratio higher than required, it will disintegrate by `beta^(-)` emission and `(n)/(P)` ratio will decrease. `._(13)^(29)Al rarr ._(14) si^(29)+._(-1)e^(0)`
