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