Write balanced nuclear equations for (a) the bombardment of ${ }_{51}^{121} \mathrm{Sb}$ by alpha particles to produce ${ }_{53}^{124} \mathrm{I},$ followed by (b) the radioactive decay of ${ }^{124}$ I by positron emission.

Key Concepts

Conservation Laws in Nuclear Reactions

In nuclear reactions, both the mass number (total number of nucleons) and the atomic number (number of protons) must be conserved. This fundamental principle is used to balance nuclear equations, ensuring that the sum of these properties remains constant before and after the reaction.

Alpha Particle Induced Reactions

Alpha particles, which are helium-4 nuclei, are commonly used in nuclear reactions due to their composition of two protons and two neutrons. Their bombardment of a target nucleus can induce a nuclear transformation, often resulting in the emission of other particles to balance the reaction.

Radioactive Decay by Positron Emission

Positron emission is a type of radioactive decay where a proton in the nucleus transforms into a neutron, resulting in the emission of a positron (a positively charged electron) and a neutrino. This decay mode decreases the atomic number of the nucleus by one while leaving the mass number unchanged, thereby forming a different element.

Balancing Nuclear Equations

Balancing nuclear equations involves ensuring that both the mass numbers and atomic numbers are equal on each side of the equation. This process sometimes necessitates the inclusion of additional particles, such as neutrons or neutrinos, to account for the conservation of nucleons and charge during the reaction.
