  2. 2. What is the atom made of? Mr. Heffner Chemistry 9/1/09
  3. 3. What is matter made of? <ul><li>Matter = stuff </li></ul><ul><li>All matter is made of atoms </li></ul><ul><li>Atoms are really small! </li></ul>
  4. 4. What is the atom made of? <ul><li>The atom is the smallest unit , but still can be divided </li></ul><ul><ul><li>The 3 subatomic particles (sub = under, less than) </li></ul></ul><ul><ul><ul><li>Proton </li></ul></ul></ul><ul><ul><ul><li>Neutron </li></ul></ul></ul><ul><ul><ul><li>Electron </li></ul></ul></ul>
  5. 5. What is charge? <ul><li>Think about magnets… </li></ul><ul><ul><li>Two sides </li></ul></ul><ul><ul><ul><li>Red = positive (+) </li></ul></ul></ul><ul><ul><ul><li>Grey = negative (-) </li></ul></ul></ul><ul><ul><li>Opposites attract ( Bill Nye Video ) </li></ul></ul><ul><ul><li>Like charges repel </li></ul></ul>
  6. 6. What is a proton? <ul><li>Proton </li></ul><ul><ul><li>Pro- = for </li></ul></ul><ul><ul><li>Charge = +1 (positive) </li></ul></ul><ul><ul><li>Mass = 1 amu </li></ul></ul><ul><ul><ul><li>Amu = atomic mass unit = 1.67 X 10 -24 g </li></ul></ul></ul>+
  7. 7. What is an electron? <ul><li>Electron </li></ul><ul><ul><li>Elect- = electricity </li></ul></ul><ul><ul><li>Charge = –1 (negative) </li></ul></ul><ul><ul><li>Mass = ~0 amu </li></ul></ul><ul><ul><ul><li>Actual mass = 9.109 X 10 -28 </li></ul></ul></ul><ul><ul><ul><li>1,600 times smaller than a proton </li></ul></ul></ul>_
  8. 8. What is a neutron? <ul><li>Neutron </li></ul><ul><ul><li>Neu- = neutral </li></ul></ul><ul><ul><li>Charge = 0 (no charge) </li></ul></ul><ul><ul><li>Mass = 1 amu </li></ul></ul><ul><ul><ul><li>Same as a proton </li></ul></ul></ul>0
  9. 9. Summary <ul><li>Atoms are made of 3 subatomic particles </li></ul><ul><li>Proton – positive (+1) and 1amu </li></ul><ul><li>Electron – negative (-1) and ~0amu </li></ul><ul><li>Neutron – no charge (0) and 1amu </li></ul>
