Structure of atom_1

  1. 1. The Structure of The Atom<br />Chapter 2<br />
  2. 2. Matter and Substance<br />Matter is anything that has mass and occupies space.<br />Made up of tiny and discrete particles (atoms, molecules and ions)<br />The smallest particle, which can participate in a chemical reaction<br />Atoms<br />Group of two or more atoms which are chemically bonded together<br />Molecules<br />Ions<br />Positively or negatively charged particles<br />
  3. 3.
  4. 4. Kinetic theory of matter<br />Explain the energy and forces between particles in matter<br />Three basic assumptions:<br />Matter is made up of _____ particles.<br />The tiny particles are in constant ______.<br />When the temperature is _______, the particles gain more kinetic energy and move in greater speeds.<br />tiny<br />speed<br />higher<br />
  5. 5. Diffusion<br />A process in which the particles of substance move and _________ the spaces in between the particles of another substance.<br />Occurs in gases, _______ and solids.<br />occupy<br />liquids<br />
  6. 6. Diffusion – Brownian Motion<br />The movement of particles in all _______ caused by the _______ among the particles or between particles and the container wall.<br />direction<br />collision<br />
  7. 7. Diffusion – Brownian Motion<br />Examples:<br />Movement of smoke particles in air<br />Movement of pollen grains in water<br />Pouring concentrated sugar solution in water<br />
  8. 8. Diffusion<br />
  9. 9. Diffusion in solid, liquid and gas<br />
  10. 10. Diffusion in solid, liquid and gas<br />
  11. 11. SOLID<br />forces<br />manner<br />low<br />
  12. 12. LIQUID<br />weaker<br />solid<br />manner<br />solid<br />
  13. 13. GAS<br />Weak<br />far<br />high<br />random<br />
  14. 14.
  15. 15. Inter-conversion of matter<br />Heating<br />Gas<br />Cooling<br />E<br />F<br />C<br />B<br />A<br />Liquid<br />Solid<br />D<br />
  16. 16. Changes in the state of matter<br />
  17. 17. Inter-conversion process<br />Melting<br />A<br />Boiling<br />B<br />Sublimation<br />C<br />D<br />Freezing<br />E<br />Condensation<br />F<br />Sublimation<br />
  18. 18.
  19. 19. Inter-conversion Processes<br />
  20. 20.
  21. 21. The heating curve of a substance<br />Temperature (°C)<br />F<br />Boiling point<br />D<br />E<br />Melting point<br />C<br />B<br />A<br />Time (Min)<br />
  22. 22. The cooling curve of a substance<br />Temperature (°C)<br />P<br />Boiling point<br />R<br />Q<br />Freezing point<br />T<br />S<br />U<br />Time (Min)<br />
