átomo de Rutherford
- According to the Rutherford atom theory, most of an atom's mass is concentrated in a central nucleus.
Examples

Morphology
The form 'Rutherford atom' is compositionally straightforward: a proper name modifying 'atom', so a learner who knows 'Rutherford' and 'atom' can infer it refers to an atom/concept associated with Rutherford. However, the specific technical content of the model (central nucleus, electron orbits) cannot be derived from the words alone and requires subject knowledge, so the expression is only partially transparent.
Etymology
Rutherford atom comes from Ernest Rutherford's gold-foil test, where most small particles passed through a thin sheet but a few were bounced back by a tiny, heavy centre inside the atom. So the strong image of a small, heavy middle with tiny negative particles moving around it explains why the Rutherford atom means a 'model' with most positive charge and mass in the centre and electrons orbiting around it.
