  1. Ions Introduction October 30, 2012

  2. DO NOW OBJECTIVE • Draw the following Lewis Diagrams in your notebook (Hint: electron dots!) • Dibuja los siguientesdiagramas de Lewis en sucuaderno • Nitrogen (N) • Neon (Ne) • Carbon (C) • Helium (He) • I can apply my understanding of ions and ioniccharge to indicate whether charged atoms are cations or anions (IC35) • Puedoaplicar mi comprensión de iones y la cargaiónicaparaindicarsi son átomoscargadoscationes o aniones (IC35)

  3. DO NOW

  4. AGENDA  50 minutes • Do Now/Objective (6 minutes) • Think About It – Potassium (4 minutes) • Octet Rule (2 minutes) • Compare and Contrast (3 minutes) • Give it a Try (7 minutes) • Vocabulary (6 minutes) • What Ion Will it Form? (5 minutes) • Pause (5 minutes) • Try a Few on Your Own (7 minutes) • Exit Ticket (5 minutes)

  5. Think About It – Potassium (K)  4 min.

  6. VOCABULARY (2 minutes) • The Octet Rule: Every element wants eight valence electrons- a full valence electron shell.

  7. Compare and Contrast (3 minutes) • How are potassium atoms different from potassium ions? • Noble Gases (Group 18) are the most stable atoms. Why is this statement true based on the octet rule?

  8. Give It A Try! (7 minutes)

  9. VOCABULARY (6 minutes) • The Octet Rule: Every element wants eight valence electrons- a full valence electron shell. • Ion: an atom that with a (+/-) electric charge; an atom that has gained or lost electrons • Ionic Charge: the (+/-) charge of an ion • Cation: an ion with a + electric charge; an atom that has lost electrons to become positive. (Cats are PAWS-itive) • Anion: an ion with a – negative electric charge; atom that has gained electrons to become negative.

  10. What Ion Will the Following Atom Form? Atomic Mass Ionic Charge Easy Electron configuration

  11. What Ion Will the Following Atom Form? • How many protons does this atom have? ______ • How many electrons does this atom have? ______ • How many electrons does this atom need gain or lose in order to fulfill a full octet? _____ • What is the electron configuration of the Li ion? _____ • Protons + Electrons = what charge? ____

  12. Pause • How many electrons does an Mg+2 have? _____ • How is this different from an Mg atom? ______ • What is the electron configuration for a Ca+2 ion? ______

  13. Try A Few On Your Own
