Question

Among the following which is an example of an artificial transmutation?

• A. ${}^{238}U{\to }^{4}He{+}^{234}Th$
• B. ${}^{27}Al{+}^{4}He{\to }^{20}P{+}_0^{1}n$
• C. ${}^{14}C{\to }^{14}N{+}_{-1}^{0}e$
• D. ${}^{226}Ra{\to }^{4}He{+}^{222}Rn$
• E. ${}_{43}^{99m}Tc{\to }_{43}^{99}Tc+\gamma$

Answer 1

The correct option is B ${}^{27}Al{+}^{4}He{\to }^{20}P{+}_0^{1}n$

${}^{27}Al{+}^{4}He{\to }^{20}P{+}_0^{1}n$ is an example of an artificial transmutation.
The conversion of one element into another by artificial means (by bombarding with some fundamental particles) is known as artificial transmutation. In the above reaction, Al is bombarded with He to form P.
