    The observations and results of Thomson's cathode ray experiment led to what change to the atomic model? (2 points) the addition of negatively charged electrons the addition of a small, positively charged nucleus the addition of neutral neutrons to the nucleus the addition of energy levels in the electron cloud I not sure on this one, going between a and d A neutral atom has an atomic number of 14 and a mass number of 30, how many protons, neutrons, and electrons are found within the atom? (2 points) 30 protons, 14 electrons, and 30 neutrons 14 protons, 14 electrons, and 16 neutrons 14 protons, 16 electrons, and 16 neutrons 30 protons, 30 electrons, and 14 neutrons This one I think it's B An atom is determined to contain 34 protons, 36 electrons, and 34 neutrons. What are the mass number and charge of this atom or ion? (2 points) mass number: 70, charge: neutral mass number: 70, charge: +2 mass number: 68, charge: -2 mass number: 68, charge: +2 And I think this one is C

    I cant remember if thomspon experiment was that of the gold foil in which some particles ended up deflecting resulting in the understanding that there is a centralized nucleus in an atom

    Ruthersfurd was gold foil, I think

    So then ya he found negative particles in his experiment via how they bent. so A.
