Question

Scientists have changed the model of the atom as they have gathered new evidence. One of the atomic models is shown below.

A large black cross in a purple circle with a black line around the purple, with 10 small green balls dispersed within the purple circle.

What experimental evidence led to the development of this atomic model from the one before it?

Answer 1

Answer: The correct answer is "A few of the positive particles aimed at a gold foil seemed to bounce back."

Explanation: This answer has been confirmed as correct.

Rutherford's experiment sent positively charged atoms into gold foil, which disproved Thompson's previous model.

Answer 2

B: The colors of light emitted from heated atoms had very specific energies.
