The question is "To explain how baryon number is conserved in alpha and beta decay"

My answer: "In beta decay, a neutrino/antineutrino is released to conserve the baryon number. Same thing works for Alpha decay"
This scored no marks but what would the actual answer be?

This is AS Physics content.

Not sure about what the new 9-1's demand.

In the beta minus decay, the net process is


 n\to p+{{\beta }^{-}}+{{\bar{\nu }}_{e}}

Both electron and anti-neutrino have no baryon number while both neutron and proton have a baryon number of 1 each.

So the baryon number is conserved for the beta minus decay.
