Notes

1) X The plum pudding model of the atoms states that: an atom is a solid, indivisible sphere that makes up all matter X
2) O Thompson developed the first model of the atom that showed the structure of the inside of an atom.
3) X Who described atoms as small spheres that could not be divided into anything smaller? Bohr X
4) X What did Bohr's model of the atom include that Rutherford’s model did not have? electron clouds X
5) O What experimental evidence led to the development of the atomic model from the one before it? A few of the positive particles aimed at a gold foil seemed to bounce back. O
6) X In what order should Jerome put these models to show the development from the earliest model of the atom to the most recent one? https://media.education2020.com/evresources/3208/3208-03/3208-03-01/3208-03-01-assessment/3208-03-01-02.png W,Y,Z,X X
7) O Why is it that being less sure about the placement of electrons in an atom is actually improvement over earlier models? Electrons don't follow specific paths, so describing the area where an electron is more likely to be is more scientifically accurate. O
8) O What is the best use of an atomic model to explain the charge of these particles in Thompson's beams? An atom's smaller negative particles are at a distance from the central positive particles, so the negative particles are easier to remove. O
9) X What did Rutherford's model of the atom include that Thompson's model did not have? energy levels X
10) X The first model of the atom was developed through: scientific experimentation and date analysis with water vapor and gases. X
11) X What did Thompson's results from experimenting with cathode rays cause a big change in scientific thoughts about atoms? His results gave people a picture of what atoms looked like for the first time. X
