Question

${}_{13}A{l}^{27}+{}_{2}H{e}^4\to {}_{15}{P}^{30}+{}_0{n}^1\to {}_{14}S{i}^{31}+{}_1{e}^0$ is example of:

• A. nuclear fusion
  
• B. nuclear fission
• C. artificial radioactivity
  
• D. none of these

Answer 1

The correct option is C artificial radioactivity

When ${}_{15}A{l}^{27}$ is bombarded with $\alpha$ particle , a radioactive isotope of phosphorous ${}_{15}{P}^{30}$ is formed with the emission of neutron.

${}_{13}A{l}^{27}+{}_{2}H{e}^4\to {}_{15}{P}^{30}+{}_0{n}^1\to {}_{14}S{i}^{31}+{}_1{e}^0$
