Chapter 6 nomenclature Flashcards
What are the four types of chemical of nomenclature we are studying?
1 binary ionic compounds
2 ternary ionic compounds (polyatomic ions)
3 binary (covalent) compounds (prefix system)
4 acids
Do we change the names are diatomic elements to dihydrogen, dioygen?
NO
How are ions formed?
By adding or subtracting electrons from neutral atoms
Explain how to write the common charge above each group of representative elements
Group one, and two are +1 and +2
after transition metals it’s +3
+/- 4
-3
-2
-1
0
What makes up a bionary ionic compound? And what charge are they?
A metal and a nonmetal 
Electrically, neutral
How do I find the oxidation number on the periodic chart?
What is the charge of the ion
group one is plus one
group 2 is +2, etc.
When writing a formula, what kind of element is written first
Metal
When writing the formula when do you reduce?
Only for ionic compounds
binary and ternary–
not covalent (2non metals)
Why do we use a Roman numeral in naming ionic compounds?
Some of the ions have more than one common charge. The Roman numerals is only used in the name of the compound, not the formula. 
What are polyatomic ions?
A group of atoms held together by covalent bonding, that carry a charge
When writing the formula, what is the difference between
binary ionic compounds
and ternary ionic compounds?
No difference in formula writing of ionic. But naming:
Both use Roman numerals, crisscross and reduce but
BINARY change anion to IDE
Do we ever mess with the official formula of a polyatomic ion?
No
Binary MOLECULAR compounds are formed from what
Two non-metals. For these, we use a prefix system. This CANNOT. Be used for ionic (contain metal and a nonmetal)
List the prefixes in order
Mono, di, tri, tetra, penta, hexa, hepta, octa, Nona, deca
A compound beginning with hydrogen is what
An acid 
If an acid anion ends in-IDE
what is the pattern and No oxygen
Hydro_______ic acid
If an acid ends in -ate
What is the pattern?
______ic acid
If an acid ends in_ite
What is the pattern?
_____ous acid
Difference between binary molecular compounds and binary ionic compounds?
Binary ionic compounds are one metal and one nonmetal
Binary molecular compounds are covalent, and ONLY Two nonmetals
How to write a formula for binary ionic?
Write the symbols
Crisscross
Reduce IF IONIC (metal + nonmetal)
NOT COVALENT
How to name, binary ionic
Right cation
Roman numeral
Anion _____-IDE
How to write ternary, ionic compounds formula
Cation symbol, anion symbol (-ate/-ite)
Right charges above
Crisscross
( ) if necessary
Naming Ternary, ionic compounds
Write cation , cover it-rest goes together
Roman numerals
Name anion (don’t change ending)
Binary molecular compounds
(covalent- 2nonmetals -prefix system)
Name it
Prefix
First element NO MONO
SECOND ELEMENT PREFIX ___-IDE
How to name acids?
Formula starts with H/
name ends with ACID
If an anion ends ____-IDE
hydro _______-IC acid
If anion ends _____-ATE
Stem of anion -IC acid
If anion ends -ITE
Stem of anion -ous acid
What’s the difference between binary, ionic and binary molecular?
Binary ionic = metal/nonmetal
Binary molecular equals two nonmetals
When doing a worksheet of mixed up compounds, what do we look for a first?
Covalent compounds. First do these prefix compounds, then nothing else has prefixes.
Cheat for naming acids:
If it’s a nonmetal, without oxygen off the chart, it will be
Hydro_____ic acid
The rest won’t have hydro , 
They’ll be _ ic
_ ous
