The following depicts two images related to atom structure. The image on the left describes an atomic theory. The image on the right describes the results of a test used to further determine the structure of the atom. Electrons scattered throughout ● (a) Expected Results D Diffuse positive charge Path of < particle Assuming that the arrows are streams of "alpha" radiation Use the image to determine whether the "alpha radiation" is positively or negatively charged. Explain how you arrived at your conclusion. Cite evidence from the image(s) in your explanation. (b) Actual Results
Classify the following statements as consistent or inconsistent with Rutherford's nuclear theory as it was originally stated. Help Reset Consistent Inconsistent A nitrogen atom has seven protons in its nucleus and seven electrons A phosphorus atom has 15 protons in its nucleus and 150 electrons outside Since electrons are smaller than protons, and since a hydrogen atom contains only one proton and one electron, it must follow that the volume of a hydrogen atom is mostly due to the proton. outside of its nucleus. of its nucleus. The majority of the mass of a fluorine atom is due to its nine electrons.

Which statement below best explains why Ernest Rutherford was expecting the alpha particles to pass through the gold foil undeflected? Rutherford expected the particles to bounce off of the electrons in the foil O Rutherford expected the gold atoms to not be densely packed together Rutherford didn't know there was a nucleus in the gold atom that the particles could bounce off of gold is very malleable
