PLEASE HELP I REALLY DO NOT UNDERSTAND THIS YOU DON'T REALLY HAVE TO ANSWER THE QUESTIONS BUT AT LEAST JSUT A LITTLE HINT THATS ALL PLEASE AND I HAVE A QUIZ ON THIS TOMORROW MY TEACHER REALLY CANNOT TEACH

Question

1) what flaws exsit in Dalton's model of the atom?
2) what flaws exist in Thompson's plum pudding model of the atom?
3) what flaws exist in Rutherford's model of the atom?
4) what flaws in Bohr's model of the atom?
5) do any flaws exist in the modern quantum model of the atom? explain.

Answer 1

Your best bet is to look at your text and go through the history of each of these theories. For example, Thompson's plum pudding model suggested that the space occupied by the atom was more or less evenly apaced; that is, electrons and protons were more or less evenly divided over the sphere of space occupied by the atom. But it could not explain the results of Rutherford's alpha particle bombardment experiments. For that reason, Rutherford proposed an atom where most of the mass was concentrated at the center of the atom (the nucleus) with electrons outside the nucleus. Neither of them knew anything about neutrons since neutrons had not been discovered at that time. That gives you a glimpse of two of them. Look in your text and go through them orderly from least complicated (Dalton) to most (quantum model) and you will see how each progressed.
