1. Compound Names and Formulas
Binary Ionic Compounds
Binary Molecular Compounds
Polyatomic Ionic Compounds
Organic Hydrocarbons
Acids

2. Binary Ionic Compounds
Compounds composed of a metal cation and a nonmetal anion
First name is the name of the metal
Second name is the name of the nonmetal with an ide suffix
Ex. NaCl is sodium chloride

3. Molecular Binary compounds
Composed of two elements both of which are nonmetals.
No ions present
First name is name of the first element with prefix
Second name is name of second element with prefix
Prefix indicates subscript number: mono, di, tri, tetra, penta, hexa, hepta, octa, nona and deca
Ex: Carbon monoxide – CO2

4. Polyatomic Ionic Compounds
Composed of metal cation and anion made up of two or more nonmetal atoms with a net negative charge
First name is name of metal cation
Second name is name of polyatomic anion
Ex. Sodium sulfate – Na2SO4

5. Organic Compounds
Hydrocarbons are made up of carbon and hydrogen atoms
Alkanes have the formula: CnH2n+2
Prefix defines the n value: n=1-9 meth, eth, pro, but, pent, hex, hept, oct, non, and dec
Name ends with ane suffix
Ex: methane – CH4

6. Binary Acids All acids contain hydrogen ion: H+
In binary acids the anions is a monoatomic nonmetal anion
Generic formula: HA
Prefix: hydro Suffix: ic
Ex. Hydrochloric acid - HCl

7. Polyatomic Acids All acids contain hydrogen ion: H+
In polyatomic acids the anion is a polyatomic anion
Generic formula: HA
Prefix: none(unless polyatomic anion name has one) Suffix: ic(ate) or ous(ite)
Ex. chloric acid – HClO3
Ex: hypochlorous acid – HClO

8. Writing formula for ionic compounds from formula
MxAy will be MyAx
Example: Calcium(2+) nitrate(1-) – Ca(NO3)2
Ammonium(1+) carbonate (2-) – (NH4)2CO3

9. Writing Molecular formula from name for binary molecular formulas
Prefix indicates subscripts for that element
Dinitrogen pentoxide: N2O5

10. Writing Alkane formula from name
Prefix indicates carbon subscript, H subscript is 2n+2
Ethane: C2H6

11. Writing Acid Formula from Name
First determine if it is binary, it will have a hydro prefix and ic suffix
All acid formulas begin with hydrogen ion
Treat them like an ionic binary compound
Determine anion element and charge
Ex: hydrosulfuric acid – H2S

12. Polyatomic acids Determine the anion and its charge
Treat it like a polyatomic ionic compound
Ex: nitric acid – HNO3
Ex: phosphoric acid – H3PO4
