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 Equation

A nuclear equation represents the transformation of one nuclide into another during a decay process. It includes the initial nuclide, the emitted particles, and the resulting nuclide, ensuring that the atomic and mass numbers are balanced. Writing a correct nuclear equation is essential for accurately depicting the decay process and understanding the changes in the nucleus.
