Question

When ${}_{13}^{27}Al$ is bombarded with $\alpha$ particles, a radioactive isotope of phosphorus ${}_{15}^{30}P$ with the emission of _____ is formed.

• A. neutrons
• B. protons
• C. positrons
• D. electrons

Answer 1

The correct option is A neutrons

When ${}_{13}^{27}Al$ is bombarded with $\alpha$ particles, a radioactive isotope of phosphorus ${}_{15}^{30}P$ with the emission of neutrons is formed.

${}_{13}^{27}Al+{}_2^{4}He\to {}_{15}^{30}P+{}_0^{1}n$
