  1. Periodic Table Ions and Oxidation Numbers

  2. Ions and Oxidation Numbers:At the conclusion of our time together, you should be able to: • Identify an ion as a cation, anion, monatomic or polyatomic • Explain the charge of an ion • Define an oxidation number • List the standard oxidation number for the periodic families

  3. Ions An ion is an atom, or group of atoms, that has a net positive or negative charge.

  4. The slightly overweight guy wished he was… Tin - Sn

  5. 11 protons 11 electrons 11 protons 10 electrons Na+ Na Cation – ion with a positive charge If a neutral atom loses one or more electrons it becomes a cation.

  6. 17 protons 18 electrons 17 protons 17 electrons Cl- Cl Anion – ion with a negative charge If a neutral atom gains one or more electrons it becomes an anion.

  7. Cation an ion with a positivecharge. Anion an ion with a Negativecharge. - A I O N

  8. A monatomic ion contains only one atom Na+, Cl-, Ca2+, O2-, Al3+, N3- A polyatomic ion contains more than one atom OH-, CN-, NH4+, NO3-

  9. Assigning Oxidation Numbers

  10. Assigning Oxidation Numbers Alkali Metals = +1

  11. Assigning Oxidation Numbers Alkaline Earth Metals = +2

  12. Assigning Oxidation Numbers Group 13 Boron Group = +3

  13. Assigning Oxidation Numbers Group 15 Nonmetals = -3

  14. Assigning Oxidation Numbers Group 16 Nonmetals = -2

  15. Assigning Oxidation Numbers Halogens = -1

  16. Assigning Oxidation Numbers Transition and Post Transition Metals generally have multiple oxidation numbers

  17. Ions and Oxidation Numbers:Let’s see if you can: • Identify an ion as a cation, anion, monatomic or polyatomic • Explain the charge of an ion • Define an oxidation number • List the standard oxidation number for the periodic families

  18. What the police did with the underage drinking parties! Radium - Ra
