PPT-Atoms and Molecules The smallest particle of an element

Examples Hydrogen Carbon Chlorine Titanium Atom Democritus 450 BC If you kept cutting a substance in half forever eventually you would end up with an uncuttable particle John Dalton 1800. Explaining how and why factors affect reaction rates. The Maxwell-Boltzmann apparatus. Maxwell and Boltzmann performed an experiment to determine the kinetic energy distribution of atoms. Because all atoms of an element have roughly the same mass, the kinetic energy of identical atoms is determined by velocity (KE= . The Building Blocks of Matter. Chapter 2. Chapter Outline. 2.1 The .
