2 Metric System ConversionsExample: cm= _____________ km

3 TRY THIS: 1000 mg = ______ g 1

4 TRY THIS: 0.15 m = __________ mm 150

5 TRY THIS: kg = __________ cg 6400

6 TRY THIS: 89 ds = __________ das 0.89

7 What is density? m ÷ ALWAYS REMEMBER UNITS! × D V

8 Let’s try a density problem togetherFrank’s paper clip has a mass of 9 g and a volume of 3 mL. What is its density? Density = Mass  Volume Density = 9 g  3 mL = 3 g/mL 9 g = 3 g 3 mL mL m ÷ × D V

9 Let’s try a density problem togetherFrank’s eraser has a density of 6 g/mL and a volume of 2 mL. What is its mass? Mass = Density × Volume Mass = 6g/mL × 2mL = 12g 6 g x 2 mL = 12 g mL m ÷ × D V

10 Let’s try a density problem togetherFrank’s shot-put has a mass of 500 g and a density of 100 g/mL. What is its volume? Volume = Mass  Density Volume = 500 g  100 g/mL = 5 mL m ÷ × D V

11 Significant Figures 56,400,000 Is there a decimal? PACIFIC (Present)ATLANTIC (Absent) Start from LEFT & count all #s from first nonzero Start from RIGHT & count all #s from first nonzero 56,400,000 4 sig figs 3 sig figs

12 You Try! How many sig figs in the following: Examples: a) 1001 kmb) m c) 129,870 m d) km e) L f) 6.02 x 1023 atoms g) 20,000 cm h) g Number of Significant Figures: a) 4 b) 4 c) 5 d) 1 e) 4 f) 3 g) 1 h) 2

13 CALCULATIONS WITH SIG FIGS SummaryMultiplying or dividing: round to the measurement with the smallest number of significant figures. 2.6 cm x 3.78 cm = cm2 Adding or subtracting: round the answer to the smallest number of decimal places. 165.5 cm + 8 cm cm = cm = 9.8 cm2 = 178 cm

20 Trends in ElectronegativityAbility of an atom to attract electrons in another atom * Fluorine has the highest electronegativity, Noble gases have ZERO electronegativity

21 Trends in Ionization EnergyThe energy required to remove an electron from an atom

22 Trends in Atomic Size Atomic Size The distance between the nucleus and the outer edge of the electron cloud

23 Ionic Bonds – electrons transferredMetals lose electrons and Nonmetals gain electrons to form an ionic bond. Properties of Ionic Compounds Crystal lattice structure High melting points Conducts electricity when melted or dissolved in water

24 Predicting Ionic ChargesGroup 1A: Lose 1 electron to form 1+ ions H+ Li+ Na+ K+ Rb+

26 Predicting Ionic ChargesLoses 3 electrons to form 3+ ions Group 3A: B3+ Al3+ Ga3+

27 Predicting Ionic ChargesNeither! Group 4A elements rarely form ions EXCEPTION: Sn and Pb!! Treat like transition metals Do they lose 4 electrons or gain 4 electrons? Group 4A:

28 Predicting Ionic ChargesNitride Gains 3 electrons to form 3- ions Group 5A: P3- Phosphide As3- Arsenide

29 Predicting Ionic ChargesOxide Gains 2 electrons to form 2- ions Group 6A: S2- Sulfide Se2- Selenide

30 Predicting Ionic ChargesGains 1 electron to form 1- ions Group 7A: F1- Fluoride Br1- Bromide Cl1- Chloride I1- Iodide

31 Predicting Ionic ChargesStable noble gases do not form ions! Group 8A:

32 Covalent Bonds – electrons sharedBond between two nonmetals. Properties of Covalent Compounds Lower melting points Does not conduct electricity when dissolved in water

33 Metallic Bonds – “sea” of electronsBond between two metals. Bond is the attraction between electrons and positive nucleus. Properties of Metallic Compounds Malleable (pounded into shapes) Ductile (pulled into wires) Conducts electricity as a solid.

34 NAMING COMPOUNDS Use roman numerals for transition metalsIONIC COMPOUNDS: Name the CATION then the ANION Use roman numerals for transition metals Example: Cu(NO3)2 copper (II) nitrate COVALENT COMPOUNDS (molecules): Use prefixes to match the subscript. Second atom name ends in “ide” Example: N2O4 dinitrogen tetroxide

35 WRITING FORMULAS Example: iron (II) chloride Fe2+ Cl- Fe 1 Cl 2 FeCl2IONIC COMPOUNDS: USE THE CROSS RULE: Example: iron (II) chloride Fe2+ Cl- Fe 1 Cl 2 FeCl2 COVALENT COMPOUNDS (molecules): Use prefixes to identify the subscripts. Example: trichloro tetrafluoride Cl3F4

36 Lewis Structure of MoleculesAdd up all the valence electrons. This is the number of dots in the final structure. Place least electronegative element in center. (Never H) Place two electrons between central and outer atoms Fill up outer atom octets. Fill up central atom octet. Make double or triple bonds if necessary so all atoms meet the octet rule. Br2 2(7) = 14
