Analogy
Atoms and radiation 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
Atoms have a small positive nucleus surrounded by electrons.
Alpha, beta and gamma radiation have different penetration and ionising powers.
Half-life is the time for activity or count rate to halve.
