Question 3

A publisher is preparing four evidence cards about the development of the atomic model.

Statement 1: Measurements of light emitted by heated atoms agreed with Bohr's calculations and supported the shell model.

Statement 2: Most alpha particles passing straight through gold foil showed that the nucleus fills most of the atom.

Statement 3: Rutherford's nuclear model placed electrons in fixed shells at set distances from the nucleus.

Statement 4: Chadwick provided evidence for an uncharged particle in the nucleus.
