4short 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 direction in beta decay?Show answer
Beta-minus increases (extra proton). Beta-plus decreases .
What is q1?Show answer
Write the balanced nuclear equation for the alpha decay of U. [2 marks]
What is q2?Show answer
A nucleus undergoes beta-minus decay followed by an alpha decay. If the parent is Co (), determine the mass number and atomic number of the final nucleus. [4 marks]
What is q3?Show answer
Refer to F beta-plus decay used at Peter Mac. (a) Write the balanced nuclear equation. (b) Explain the origin of the keV photons detected.
