can give EXPLAINATION FOR RUTHERFORD ATOMIC THEORY
Answers
Explanation:
Ernest Rutherford was a scientist born in New Zealand and won the Noble Prize in Physics. He worked under JJ Thomson. He conducted the gold foil experiment. He basically sent positively charged particles at a gold foil (very thin gold foil). The gold foil was placed in front of a circular fluorescent screen to detect the alpha particles. Most of the rays just passed through the middle. Some of the rays bounced back and some deflected.
- Since most rays passed through the middle, he thought that there was an empty space in the middle.
- Since some rays deflected, he thought that positively charged particles are in the middle, and the rays deflected due to repulsion (same charged particles don't go together).
- Since some rays bounced back, he thought that the positively charged particles are small.
Based on this experiment, he passed a theory that in the middle of the atom, there exists a nucleus, a positively charged mass.
As to the way the electrons, neutrons, and protons are positioned, he passed another theory that the atom functions like the solar system, where the electrons are the planets, moving around the nucleus, which was compared to the sun. The scientists, however, pointed out that if electrons were negative and the nucleus was positive, they would stick together. Hence, this theory was disregarded by some. But it was later identified to be partly correct, due to Bohr's atomic theory, which is for another time.
Hope this helped, please put forward any other questions you have, I am preparing for the exams too.
