Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Nuclear Decay

Nuclear decay is the process by which an unstable atomic nucleus loses energy by emitting radiation. This can occur in various forms, including alpha decay, beta decay, and positron emission. Understanding the type of decay is crucial for writing accurate nuclear equations, as it determines the particles emitted and the resulting nuclide.

Positron Emission

Positron emission is a type of beta decay where a proton in the nucleus is transformed into a neutron, resulting in the emission of a positron (the antimatter counterpart of an electron) and a neutrino. This process decreases the atomic number of the nuclide by one while keeping the mass number unchanged, leading to the formation of a new element.

Nuclear Equations

Nuclear equations represent the transformation of one nuclide into another during radioactive decay. They are written to show the initial nuclide, the emitted particles, and the resulting nuclide. For positron emission, the equation will include the original nuclide, the emitted positron, and the new nuclide formed after the decay.
