Nomenclature• Naming Chemical Compounds– Three Types:

Nomenclature• Type A: Ionic
• Metals with known charge + Nonmetals
![Page 4: Nomenclature and Mixtures Naming Compounds, Identifying Mixtures, Separation Techniques.](https://reader036.fdocuments.us/reader036/viewer/2022082404/56649ea25503460f94ba5667/html5/thumbnails/4.jpg)
Nomenclature• Type B: Ionic
• Metals with UNKNOWN charge + Nonmetals

Nomenclature• Type C: COVALENT
• Nonmetal + Nonmetal

Let’s Practice, Shall We??
• Name the following using Type A rules:
• LiCl• MgI2
• Na2O
• Now go the other way:• Beryllium Nitride• Calcium Selenide• Hydrogen Chloride (a.k.a. hydrochloric acid)

Let’s Practice, Shall We??
• Name the following using Type B rules:
• Fe2O3
• FeO• CrCl2
• Now go the other way:• Manganese (I) Bromide• Nickel (II) Phosphide• Cobalt (III) Selenide

Let’s Practice, Shall We??
• Name the following using Type C rules:
• CO2
• CO• N2O3
• CCl4
• And, yes let’s go backwards one last time• Sulfur Dioxide• Trinitrogen Hexaoxide• Oxygen Dichloride

Nomenclature
• Practice:– Chromium (III) Chloride– Li2O– Rubidium Oxide– Dihydrogen Monoxide– Trinitrogen Hexaoxide– Iron (II) Fluoride

Polyatomics
• Sames rules apply– Just cancel out the charges
– These use Type A and B rules, NOT Type C
– NEVER USE A PREFIX WITH POLYATOMICS!!
– Try:• Iron (III) Hydroxide RbOH• Potassium Nitrate Li2SO4
• Hydrogen Sulfate HNO3
• Hydrogen Sulfide Na3PO4

Nomenclature,IN A NUTSHELL
• Type A: (works with polyatomics too)– Must know the charge– Cancel the charges out and name it– Add –ide to the end
• Type B: (works with polyatomics too)– MUST use a Roman Numeral (tells us the charge)– Then name just like “A”– NEVER, EVER, EVER!!!! USE A PREFIX!!! EVERRR!!
• Type C: (a polyatomic is metal so they CANNOT be used here two nonmetals only!!– MUST use a PREFIX, ONLY with two nonmetals!!
