Answer: Rutherford's experiment weakened the plum pudding model. Rutherford's model proposed the atom as planetary, the nucleus in the middle with the negative particles going around it. This model is far different from the plum pudding which proposed the atom to positively charged with the negative particles uniformly stuck in it.

Answer:

Thompson discovered the electron  and also stated that these electron are not found with in the nucleus of an atom which is contrasting to his plum pudding theory

Explanation:

J. J. Thomson has used a cathode ray tube to conduct his experiment. He projected the cathode rays towards positively charged alpha particles at thin gold foil and found that all the cathode rays have easily passed through this foil carrying positive charge but when the same rays were projected to a negative metal plate , the cathode rays moved away from the metal plate. Through this observation, Thompson concluded that cathode rays are negatively charged and there is something negative with in a matter that he later termed as electron which are not confined with in the nucleus of atom but they revolve around the nucleus. However, in pudding model he said that atom is a positively charged pudding with electrons embedded in it.

What is Noah's principle?
Karo-lina-s [1.5K]
Noah's principle is a concept that comes from the Biblical story found in the old testament where God gave Noah instructions to build an ark to save him and his family . The concept here is that God did not tell Noah when it was going to rain. The people of the day most probably mocked and derided Noah as a time waster or a fool. That is, until the flood came. The " fool" had been wiser all along. An Application is this. Google gives everyone who does online business "suggestions" and "guidelines" but not everyone chooses to listen. Google rarely, if ever, tells us when they will put the guidelines into action. Panda, a Google ranking system, took 6 years while Google was telling online users to follow certain guidelines. Many ignored, until Panda was put into action, and those who had not heeded suffered with only themselves to blame. Moral: Heed and prepare even if the outcome tarries.
