  2. 2. Periodic Table:<br />Chart that shows various FAMILIES of elements<br />Arranged into ROWS and COLUMNS<br />Rows: across<br />Columns: down<br />
  3. 3. 3. THREE categories (pieces of information) found on the Periodic Table:<br />Symbol – represents a specific element<br /> - Ex. H is what element?<br /> -HYDROGEN<br />
  4. 4. b. Atomic Number – table is organized and arranged from left to right by increasing atomic number.<br /> **Element’s ID<br /><ul><li>Atomic Number = # of PROTONS = # of ELECTRONS</li></li></ul><li>Ex. H<br />Atomic Number<br />
  5. 5. Ex. S<br />
  6. 6. Ex. S<br />
  7. 7. Ex. K<br />
  8. 8. Ex. K<br />
  9. 9. c. Mass Number – Most of the mass of an atom is in the nucleus<br /><ul><li>Mass number is usually found under the element symbol
