Question

question 17 1 pts what type of radiation is present in the following nuclear decay reaction: ^{17}_{9}f→^{13}_{7}n + ^{4}_{2}he alpha gamma beta

Explanation:

In nuclear decay, an alpha - particle is a helium - 4 nucleus ($^4_2He$). The given reaction shows a fluorine nucleus decaying into a nitrogen nucleus and a $^4_2He$ particle. Alpha decay involves the emission of an alpha - particle. Gamma radiation is electromagnetic radiation usually emitted along with other types of decay and is not a particle emission like in this case. Beta decay involves the emission of an electron or a positron. Since a $^4_2He$ particle is emitted here, it is alpha decay.

Answer:

A. Alpha
