A) Bohr claimed atoms were indivisible B) Bohr said electrons were in the nucleus C) Bohr ignored the nucleus D) Bohr placed electrons in energy levels
A) Correct, as Bohr proved this model. B) Correct, because electrons never change orbits. C) Correct, because electrons have fixed paths. D) Incorrect, because electrons move in regions of probability.
A) Both are correct since both are charged. B) Student B, because electrons change easily. C) Student A, because protons determine atomic number. D) Neither, because neutrons define the element. |
