1. Homework Statement
27-Al disintegates to form 29-Al, by what emission this is possible?

a)alpha b)beta c)positron d)proton

2. Homework Equations
beta results in atomic no. increase,alpha results in both mass &no. decrease,positron results in decrease in no.,proton results in decrease by 1 in both.


3. The Attempt at a Solution
the answer i think given is wrong as we want a paricle like neutron to make it happen (which is not in the options)

are answers and options wrong or just my basics are being tested?

This is really late, but for what it's worth, your thinking is correct and the question is wrong (besides, Al-27 is the stable isotope - it does not decay).
