CH 301 Chapter Notes - Chapter 1: Plum Pudding Model, Electromagnetic Radiation, Spectroscopy
Document Summary
Hydrogen molecules form a bond that is 74 picometers away from one another because that is the most stable place to be energetically. Jj thomson: found that electrons exist, plum pudding model- model where there is a cuttable atom" with a pudding middle and electrons floating around. Rutherford: shot alpha particles into gold foil and found that electrons are far away from the nucleus of an atom. Bohr: found that electrons are found in orbitals. Scrodinger: made a wave function for particles, if you square the wave function, then you find out where the particle is located. Light is truly a wave: if a wave of light is at the same frequency as another wave, the frequency and wave would keep increasing and get excited until the light wave leaves. Spectroscopy: investigating what is going on in chemical and biological systems.
