In Rutherford's experiment, the outcomes areA. By classical electrodynamics, the atoms will not be stable while radiating photonB. All incident alpha particles scattered only less than 5 degreesC. Electrons revolve around the nucleusD. There is a nucleus at the center

The outcomes of Rutherford's experiment are:

1. The discovery that atoms have a small, dense, positively charged nucleus at the center. This was a significant departure from the previously accepted plum pudding model, which suggested that atoms were a uniform blend of positive and negative charges.

2. The realization that electrons revolve around the nucleus. This was another significant finding that helped shape the modern understanding of atomic structure.

3. The observation that not all incident alpha particles scattered at small angles. While most alpha particles passed straight through the gold foil used in the experiment, a small number were deflected at large angles. This was unexpected and led to the conclusion that the positive charge within an atom is concentrated in a very small area (the nucleus).

4. The understanding that, according to classical electrodynamics, atoms would not be stable while radiating photons. This was a problem that was later resolved by the development of quantum mechanics.

So, the correct outcomes are C and D. Options A and B are not correct. Option A is a problem that was recognized but not an outcome of Rutherford's experiment. Option B is incorrect because not all alpha particles scattered at small angles.
