|
Binary Covalent Compounds (Type III) are formed between _________
|
nonmetals
|
|
named the rules for the naming of Binary Covalent Compounds (Type III)
|
rules:
The first element in the formula is named first, using the full element name The second element is named as if it were an anion Prefixes are used to denote the number of atoms present. The prefix mono- is never used for naming the first element |
|
a solution produced by certain molecules containing free H+ ions
|
acids
|
|
what are the rules for naming acids?
|
if the anion does not contain oxygen, the acid is named with the prefix hydro- and the suffix -ic.
When the anion contains oxygen, the acidic name is formed from the root name of the anion with a suffix of -ic or -ous, depending on the name of the anion. If the anion name ends in -ate, the suffix -ic is added to the root name. If the anion has an -ite ending, the -ite is replaced by -ous |
