Dalton and lavoisier

  1. 1. Dalton and Lavoisier<br />A New Dawn for Chemistry:<br />
  2. 2. Conservation of mass and atomic theory<br />Dalton – Atomic Theory<br />Lavoisier – Conservation of Mass<br />
  3. 3. John Dalton’s new Atomic Theory<br />Lavoisier’s Conservation of mass<br />
  4. 4. Atomic Theory - 1<br />The atoms of a given element are different from those of any other element; the atoms of different elements can be distinguished from one another by their respective relative atomic weights.<br />
  5. 5. Atomic theory - 2<br />All atoms of a given element are identical.<br />Carbon Atoms<br />
  6. 6. Atomic theory - 3<br />Atoms of one element can combine with atoms of other elements to form chemical compounds; a given compound always has the same relative numbers of types of atoms.<br />
  7. 7. Atomic theory - 4 <br />Atoms cannot be created, divided into smaller particles, nor destroyed in the chemical process; a chemical reaction simply changes the way atoms are grouped together.<br />Based on Lavoisier’s Law of Conservation of Mass<br />
  8. 8. Atomic theory - 5<br />Elements are made of tiny particles called atoms. <br />Atom – from the Greek word “atmos,” meaning “indivisible”<br />
