Question

1. given the reaction:

27/13 al + 4/2 he → 30/15 p + 1/0 n.

this reaction is best described as

a. beta decay

b. artificial transmutation

c. fission

d. fusion

a
b
c
d

Explanation:

• Beta decay involves the emission of a beta particle (\(\beta\)) from a nucleus. In this reaction, it is not the case.
• Artificial transmutation is the conversion of one element into another by bombarding its nucleus with high - energy particles. Here, \(\ce{^{27}_{13}Al}\) is bombarded with \(\ce{^{4}_{2}He}\) (alpha particle) to form \(\ce{^{30}_{15}P}\) and a neutron (\(\ce{^{1}_{0}n}\)), which fits the definition of artificial transmutation.
• Fission is the splitting of a heavy nucleus into lighter nuclei. This reaction is not a fission reaction.
• Fusion is the combining of light nuclei to form a heavier nucleus. This is not a fusion reaction as well.

Answer:

B. artificial transmutation
