Understand this objective

Short explanation

Within Nuclear equations, this learning objective asks you to explain that gamma emission does not change mass number or atomic number. Focus on the approved ideas mass number, gamma emission, atomic number and connect them clearly to Atoms and nuclear radiation. A strong response should state the relevant particle, radiation, isotope, decay, half-life or nuclear-equation idea, then explain how it answers the exact command word. Avoid swapping nearby concepts such as atomic number and mass number, isotope and ion, alpha, beta and gamma radiation, or contamination and irradiation.
