Here are answers to [[CP Homework After Dalton thru Bohr]].<br> <br> 1a) JJ Thompson experiment:<br> *He added high energy to two pieces of metal in a vacuum and it produced a green glow. *He then put a magnetic on one need and the green glow bend away from "-" end of magnetic. *He changed the power of magnetic and green glow bend more or less depending on power of magnetic.<br> <br> 1b) What did the results of his experiment explain with respect to atom.<br> *Green glow was not light. * It must be a particle that came from inside atom of metals. *Particle is negatively charge. *We call it an electron.<br> <br> 1c) Plum Pudding Model, atom is made of electron (negatively charged particles) and rest of atom is postively charged.<br> <br> <br> 2a) oil dropping, electron's actual mass and charge<br> <br> 2bi) proton (p<sup>+</sup>), located in nucleus, 1.67E-24g<br> 2bii) electron (e<sup>-</sup>), located outside nucleus, 9.11E-28g<br> 2biii) neutron (n<sup>0</sup>), located in nucleus, 1.67E-24g<br> <br> 3) Goldstein<br> <br> 4) Chadwick<br> <br> 5a) see notes<br> 5b)<br> *Rutherford "shot" small "+" bullets at gold leaf (closest to 1 atom thick) and surround gold leaf in 3 dimensions with coated paper that glowed "green" when hit by "+" bullet. * Coated paper used degrees of deflection to indicate where "+" bullet hit it. 0 degree deflection = straight thru gold leaf and >90 degree means bounce back from gold leaf. <br> *Found a few bounced back that indicated that there is something small volume, massive (most mass of atom) and "+" charge.<br> <br> 5c) nucleus = small volume, massive and "+" charge.<br> 5di) CP does not do <br> 5dii) CP does not do<br> 5e) see notes<br> <br> 5e) electrons are outside of nucleus (where protons and neutrons are located).<br> <br> 6a) Electrons<br> <br> 6b) ENERGY of an electrons = DISTANCE AWAY FROM NUCLEUS of electron.<br> <br> 6c) see notes<br> <br> 6d) <br> *Atom in Ground State (all electrons in lowest energy level available) *Atom absorbs specific energy packet size that is used for an electron to go from a lower energy to a higher energy level. **Atom is now in excited state (NOT all electrons in lowest energy level available). *Instantly, electron falls back down to original lower energy level (atom back in Ground state). *Atom emits that specific energy packet size from atom <br> <br> 6e) Electron still revolve (in their energy level though) around nucleus like planets around sun.<br> <br>
