Understanding Nuclear Decay: The Role of Beta Emission in 27-Al Disintegration

[krateesh]

Homework Statement

27-Al disintegates to form 29-Al, by what emission this is possible?

a)alpha b)beta c)positron d)proton
answer given- beta

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.

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).
