Rutherford’s nuclear atom revisited

What use are theories?

Derek Jacobs explains how physicist Henry Moseley used theories about atomic structure and energy, together with experiments involving X-rays, to predict several new elements

The terms in bold link to topics in the AQA, Edexcel, OCR, WJEC and CCEA A-level specifications, as well as the IB, Pre-U and SQA exam specifications.

Theories involving atomic energy levels, energy of X-ray photons, atomic number and the nuclear model of the atom, coupled with some ingenious and careful experimental measurements, led to the prediction of new elements.
