4.5.112 - Alpha scattering and the nuclear atom

Understand how large-angle alpha particle scattering gives evidence for a nuclear model of the atom and how our understanding of atomic structure has changed over time.

Use - alpha scattering and the nuclear atom to connect the rule to the data and decision in the question.

This matters because - alpha scattering and the nuclear atom determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply - alpha scattering and the nuclear atom to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: - Alpha scattering and the nuclear atom is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
