1. Ions

2. Ions atoms of a given element that differ in the number of electrons, …and consequently in overall charge.

3. Ions periodic patterns regarding ions

4. Ions metal ions vs.nonmetal ions

5. Working with Atomic Notation A Z X # Chemical Symbol Ionic Charge or “Oxidation Number”

6. Working with Atomic Notation 35 17 Cl -1

7. Working with Ionic Notation Cl - 1

8. Working with Atomic Notation 23 11 Na +1

9. Working with Ionic Notation Na +1

10. Ions Anion –Negatively charged ion. Cation –Positively charged ion.

13. # of p + # of n o # of e - # of p + # of n o # of e - neutral Lithiumionic Lithium 3Li Lithium 6.941

14. # of p + # of n o # of e - # of p + # of n o # of e - Chlorine Chlorine…the neutral atom Chlorine Chlorine…the ion 17Cl Chlorine 34.453

15. 11Na Sodium 22.990 # of p + # of n o # of e - # of p + # of n o # of e - Sodium Sodium…the neutral atom Sodium Sodium…the ion

16. Octet Rule The octet rule says that atoms tend to gain, lose or share electrons so as to have eight electrons in their outer electron shell.

17. Transition Metal Ions Transition Metal Ions are different than other metal ions. 1) There are no predictable patterns that can be used to determine their ionic charges Yes, they are all positive but… 2) A good number of transition metal elements possess an ability to have more than one positive ion.

18. 1) There are no predictable patterns that can be used to determine their ionic charges

19. Fe +2 Mn +7 Co +2

20. 1) There are no predictable patterns that can be used to determine their ionic charges Ag +1 Cu +2

21. 2) A good number of transition metal elements possess an ability to have more than one positive ion. Fe +3 Fe +2

22. 2) A good number of transition metal elements possess an ability to have more than one positive ion. Al +3

23. 2) A good number of transition metal elements possess an ability to have more than one positive ion. Mn +3 Mn +2 Mn +4 Mn +5 Mn +7

24. Working with Ions (practice) atomic (ionic) notation # of p + # of e - # of n o Ca o Ca +2 N o N -3

25. Working with more Ions (practice) name atomic (ionic) notation # of p + # of e - # of n o the ion of magnesium the ion of oxygen the ion of fluorine the ion of lithium

26. Review problem Draw the following ions and (neutral) atoms using the Octet Rule/Model of the atom. (Valence Shell Only) a) Ne o b) Mg +2 c) Na +1 d) N -3

27. Working with Ions (more practice) atomic (ionic) notation # of p + # of e - # of n o K o K +1 I o I -1

28. Naming Ions Predictable Metal Ions, Unpredictable Transition Metal Ions, and Nonmetal Ions are named differently

29. Naming Ions Nonmetal IonsMetal Ions Non Transition Metal Ions Transition Metal Ions

30. metal ions vs.nonmetal ions Naming Ions keep the atoms elemental name …add the word ion keep the atoms elemental root …drop the ending …add the suffix –ide. (using the word ion is redundant and not acceptable when naming nonmetal ions)

31. The Stock System Naming Transition Metal Ions -Use the complete elemental name (as expected). -Use roman numerals to designate the ionic charge or oxidation number of the transition metal ion. -Use the word ion to designate its ionic nature.
