It should be described that the experimental basis for believing that the nucleus occupies a very small fraction of the volume of the atom. Concept introduction: Atom is the smallest particle of a chemical element that can exist. Atom contains positively charged proton, negatively charged electron and neutrons without any charge. Proton and neutron collectively referred as nucleons those are present inside of the nucleus. According with the Rutherford’s α - particle scattering experiment, Rutherford bombarded gold foil with α - particles and most of them passed through the foil, whereas a small proportion were deflected or reflected. Thus most of the atom must be empty space through which the α - particles could pass without encountering any obstructions.

Question 11 of 18 (1 point) Question Attempt: 3 of How many signals do you expect in the 'H NMR spectrum for this molecule? Br Br Write the answer below. Also, in each of the drawing areas below is a copy of the molecule, with Hs shown. In each copy, one of the H atoms is colored red. Highlight in red all other H atoms that would contribute to the same signal as the H already highlighted red. Note for advanced students: In this question, any multiplet is counted as one signal. Number of signals in the 'H NMR spectrum. 1 For the molecule in the top drawing area, highlight in red any other H atoms that will contribute to the same signal as the H atom already highlighted red. If no other H atoms will contribute, check the box at right. No additional Hs to color in top molecule Check For the molecule in the bottom drawing area, highlight in red any other H atoms that will contribute to the same signal as the H atom already highlighted red. If no other H atoms will contribute, check the box…
