Transcript

  • 1. The Periodic Table<br />
  • 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. 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. 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. Ex. S<br />
  • 6. Ex. S<br />
  • 7. Ex. K<br />
  • 8. Ex. K<br />
  • 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
  • 10. Can be found by </li></ul> ADDING the PROTONS <br />and NEUTRONS<br />
  • 11. Mass # = protons + Neutrons<br />Ex. H<br />1 proton + 0 Neutrons = _______<br />Ex. Li<br />3 protons + 4 Neutrons = _______<br />Ex. Al<br />13 protons + 14 Neutrons = _______<br />
  • 12. Mass # = protons + Neutrons<br />How can you find the number of neutrons in Phosphorus?<br />Mass # = ______<br />#Protons= ______<br />__________________<br /># Neutrons=<br />
  • 13. Mass # = protons + Neutrons<br />How can you find the number of neutrons in Phosphorus?<br />Mass # = 31<br />#Protons= 15<br />__________________<br /># Neutrons= 16<br />
  • 14. 4. Bohr Models<br />a. Model of the atom that shows protons, neutrons, electrons, and energy levels<br />
  • 15. 4. Lewis Dot Structures<br />a. Model of the atom that shows the VALENCE electrons of the atom<br />
