  19. Ions OBJECTIVE: See connection between electron configuration and chemical properties

  20. Ions What is an ION? an atom that gained or lost one or more electrons

  21. Ions What is an ION? an atom that gained or lost one or more electrons 1. What determines if an atom gains or loses an electron 2. What determines how many electrons are gained or lost

  22. Valence Electrons and Ions What are valence electrons? electrons in its outermost orbital

  23. Valence Electrons and Ions Write FULL electron configuration for Silicon, Si

  24. Valence Electrons and Ions Write FULL electron configuration for Silicon, Si

  25. Valence Electrons and Ions Write FULL electron configuration for Silicon, Si Si = 1s22s22p63s23p2

  26. Valence Electrons and Ions Write FULL electron configuration for Silicon, Si Si = 1s22s22p63s23p2

  27. Valence Electron and Ions Write FULL electron configuration for Germanium, Ge

  28. Valence Electron and Ions Write FULL electron configuration for Germanium, Ge Ge = 1s22s22p63s23p24s23d104p2 4 valence electrons

  29. Valence Electron and Ions • Write the electron configuration for the following elements • UNDERLINE valence electrons

  30. Valence Electron and Ions The S orbital can hold how many electrons? TWO The P orbital can hold how many electrons? SIX Noble gases are stable and unreactive because their outer orbitals are FILLED

  31. Valence Electron and Ions Alkali and Alkali Earth Metals want to be noble by having the SAME electron configuration

  32. Textbook page 162 • Ions with at POSTIVE charge, +, are • called • cations • pronounced “cat – ions”

  33. Ions • IMPORTANT • Ions and their parent atoms have different properties. • Ex: a Li cation =/= a Li atom • Why might this be the case? • Just because ions have the same electron configuration as Noble Gases does not make them become Noble Gases. • Ex: a Li cation =/= He atom • Basic idea: • ions not same as parent atom • ions do not become Noble Gases

  34. Textbook page 163

  35. Valence Electron and Ions Non-Metals want to be noble by having the SAME electron configuration

  36. Textbook page 162 • Ions with at NEGATIVE • charge • called • anions • pronounced “an – ions”

  37. Textbook page 162 • Ions with at NEGATIVE • charge • called • anions • pronounced “an – ions”

  45. Ions So far we learned how a “normal” atom becomes an ion Li  Li+ + 1electron Mg  Mg2+ + 2electrons N + 3electrons  N3- O + 2electrons  O2- F + electron  F-

  46. Ions Some ions are made from two or more atoms Ex: CN- NH4+ CO32- Because these ions are made from two or more atoms, they are called polyatomic ions

  47. Ions Because these ions are made from two or more atoms, they are called polyatomic ions -itehas less oxygen than-ate

  48. Ions, Ionic Bonds, and Ionic Compounds OBJECTIVE: Understand how IONS join together to create IONIC COMPOUNDS

  49. Ions, Ionic Bonds, and Ionic Compounds Ionic Bonding Ionic bonds form between cations and anions, ions with opposite charges Na+ + Cl- NaCl cation anion ionic compound
