3short Q&A pairs drawn directly from our worked dot-point answer. For full context and worked exam questions, read the parent dot-point page.
What is wrong $Z$ direction in beta decay?Show answer
Beta-minus increases $Z$ (extra proton). Beta-plus decreases $Z$.
What is treating gamma emission as changing the element?Show answer
Gamma keeps both $A$ and $Z$ unchanged.
What is forgetting the neutrino?Show answer
For full marks, include it. The antineutrino in beta-minus accompanies the electron; the neutrino in beta-plus accompanies the positron.
