Analogy
Nuclear equations is like tracking a system with arrows and numbers: decide what changes, what stays conserved, and what equation describes it.
Why now: An analogy helps when the definition feels abstract.
Do this: Match each part of the analogy to the science idea.
Learn it
Alpha decay reduces mass number by 4 and atomic number by 2.
Beta decay increases atomic number by 1.
Nuclear equations must balance mass number and atomic number.
