| Binary compounds (I & II) |
|
Definition
Compounds made of 2 different elements
Binary I- Metal and non-metal elements
Binary II- Non-metal and non-metal elements |
|
|
Term
| Naming Binary I compounds |
|
Definition
1) Name of cation first
2) Name of anion second (take element name and change the ending to -ide) |
|
|
Term
|
Definition
Type I- Cation only has one charge
Type II- Cation can have more than one charge |
|
|
Term
| Naming Type III Binary Compounds |
|
Definition
1) First element in the formula is named first, and full name is used
2)Second element is named as though it were an anion
3)Prefixes are used to denote the #s of atoms present
4)Prefix mono- is never used to name the first element (implied) |

Definition
Binary Compound?
I
Yes
I
Metal Present?
-----------------------I-----------------
I I
No Yes
Type III (Use prefixes) Does the metal form more than one cation?
------------------------------------I--------
I I
No Yes
Type I use element name Find cation charge; Use roman numeral |

Term
|
Definition
| 3 or more elements present (must be a polyatomic ion present) |
|
|
Term
|
Definition
| Multiple atoms chemically bonded together in a grouping |
|
|
Term
| Naming Polyatomic compounds |
|
Definition
| Name sameway as Type I and II. Only difference is polyatomic ions name never changes, nor does it ever get Roman Numerals |
|
|
Term
|
Definition
1) Name anion first
2) Change name of anion accordingly
Endings:
-ides change to (hydro-)anion(-ic)
-ates change to anion(-ic)
-ites change to anion(-ous)
Only named as acids if it has (aq)
Ex: HCL(g)-Hydrogen monochloride
HCL(aq)-Hydrochloric acid |

|
Term
| Writing Formulas from names |
|
Definition
1)Write the symbol for cation first
2)Write symbol for anion second
3)Use subscripts to cancel charges |
