Worked Solution & Example Answer:Which radioactive decay equation is correct? A - OCR Gateway - GCSE Physics - Question 12 - 2019 - Paper 1
Step 1
Identify the correct radioactive decay equation
Answer
In radioactive decay, the original nucleus transforms into a different nucleus while emitting particles. The correct equation involves the transmutation of Carbon-14 () to Nitrogen-14 () with the emission of a beta particle (electron, ). Thus, the correct option is:
D. ^{14}_{6}C \rightarrow \; ^{14}_{7}N + \; _{-1}^{0}e
