16 $800 What is the charge on the polyatomic ion? This is what the sum of all the oxidation numbers in a polyatomic ion must equal.

26 $800 What is ferrocyanate nitrate? This is the name for this compound: FeSCN(NO 3 ) 2.

27 $1000 What is “-ite?” Polyatomic oxyanions come in pairs and this is the suffix on the ion with the lesser number of oxygens.

28 $200 What are covalent network crystalline compounds? The solid compounds in this particle structure category are usually harder than those in all others.

29 $400 What is a polar covalent compound? This is the category of compound in which the particle structure of water fits.

30 $600 What are ionic compounds? Except for covalent network structures, this is the category of structural particles in compounds that results in solids that are typically hardest to melt or boil.

31 $800 What are nonpolar covalent compounds? At room temperature and pressure compounds in this particle structure category tend to be gases.

32 $1000 What is ionic or crystalline? The particle structure category in which this compound fits: (NH 4 ) 3 PO 4

33 $200 What is a molecular formula? This kind of formula shows the actual number of atoms in a molecule.

34 $400 What is an empirical formula? This formula shows the lowest whole number ratio of the atoms in a molecule.

35 $600 What is a structural formula? This kind of formula shows how atoms are connected together in a compound, especially in a molecule or polyatomic ion.

36 $800 What is a complete structural formula? This is the kind of structural formula pictured here.

37 $1000 What is a skeletal structural formula? This is the kind of structural formula pictured here.

38 $400 What is 0 to 0.3? This is the range of electronegativity difference that typically results in a non- polar bond.

39 $800 What is a molecule or molecular center in which all the surrounding atoms have about the same electronegativity? These are the conditions in which polar bonds in a tetrahedral molecular shape will NOT result in a polar molecule or structural center.

40 $1200 What is a partially positive charge? This is what the symbol δ+ means to a chemist.

41 $1600 What is a δ  ? This is what a molecule or molecular center must ALSO have IF it has a δ+.

42 This is why ionic compounds can never be polar. $2000 Ionic particles are separate positive or negative while polar particles are single particles with partial positive and negative poles?

43 $400 What are crystals or a crystalline structure? This is the kind of structure that ionic compounds typically form when they are pure substances.

44 $800 What is a crystal or crystalline structure? This is the kind of structure that a covalent network forms if the particles are allowed to solidify slowly.

45 $1200 What is a molecule? These are the structural units in a molecular solid.

46 $1600 What is polarity? This is what a molecule must have so that it can form crystals when solidified slowly.

47 $2000 What is covalent? This the type of internal structure (between atoms) in a polyatomic ion.

48 $400 What is ethanol? This is the name of the chemical the structure which is illustrated here.

49 $800 What is benzene? This is the name of the chemical illustrated here.

50 $1200 What is a heptan-3-one? The name of the chemical illustrated here.

51 $1600 What is butyl ethyl ether? This is the name of the chemical illustrated here.

52 $2000 What is 2-fluoro-3-methyl-butanoic acid? This is the name of the chemical illustrated here.

55 $1200 What is an aldehyde? This is the functional group in this illustration.

56 $1600 What is an amide? This is the most important functional group in this illustration.

57 $2000 What is a halide or halo group? This is the class of functional groups in the compounds represented here.

58 $400 What are polyatomic ions? These are charged groups of covalently bonded atoms that act like single atoms in forming ionic compounds.

59 $800 What is a tetrahedral? This molecular center has 4 single bonds and no lone pairs.

60 $1200 What are polar bonds? A polar molecule with a trigonal pyramidal shape must have these.

61 $1600 What is an imbalance in polarity among the bonds? A polar tetrahedral molecule must have these.

62 $2000 What is never? This is when a molecule that has nothing but non-polar bonds can be polar.

63 $400 What are ionic compounds? These compounds typically don’t conduct electricity until they are either dissolved in water or melted.

64 $800 What are covalent compounds? The kinds of compounds, when they are solid, are— relatively speaking—softer than ionic compounds.

65 $1200 What are covalent compounds? For the most part, these compounds have a lower melting point and a lower boiling point than ionic compounds.

66 $1600 What are covalent network crystal compounds? These kinds of compounds are even harder than ionic compounds.

67 $2000 What is they form crystals with an almost infinite number of ions? This is why you simply cannot write a formula that shows the actual number of atoms in a particle of an ionic compound.

68 Daily Double What are polar covalent compounds? These are compounds with bonds in which the electrons are NOT equally shared?

69 Daily Double What are “polyatomic oxyanions?” This name identifies molecule-sized particles that have a negative charge and also contain oxygen.

70 Daily Double What is “-ide?” Unless it’s an acid or an organic compound, this is the suffix for a binary compound.

71 The Jeopardy champion!
