Nomenclature

1
Nomenclature

• Its like a secret handshake

2
Ionic substances

• Held together by opposite charges
• Contains a cation(a positive ion) and an anion (a
  negative ion)
• Formula must be neutral

3
Metal and a Nonmetal

• Binary ionic compound
• Type IMetal has one charge only (not a
  transition metal)
• Cation first, anion last
• -ide ending on anion only
• Ex MgI2

4

6
Name each Compound

• RbF
• Rubidium Fluoride
• K3N
• Potassium Nitride
• MgBr2
• Magnesium Bromide

7
Metal and a Nonmetal

• Binary ionic compound
• Type II Metal that has two or more with 2 or
  more DIFFERENT charges(transition metals)
• Cation first, anion last
• -ide ending on anion only
• Show charge of cation
• Roman numeral in the name only
• Ex HgO

8
Whats the Name?

• Iron(III) and Oxygen
• Iron(III) Oxide

• MnO2
• Iron(III) and Oxygen
• Fe2O3

10
Polyatomic ions

• Same rules for binary ionic substances-held
  together by charge
• Contains ions that have 2 or more different atoms
• Ends in ate when oxygen is present in the anion

11
Polyatomic Ions
12
Memorize

• The most commonly used polyatomic ions, their
  composition and their charge
• Learn
• Nitrate, carbonate, sulfate, phosphate, acetate,
  hydroxide, and ammonium

13
Examples

• NH4OH
• ammonium hydroxide
• Magnesium acetate
• Mg(C2H3O2)2

14
Name the Compound

• CaCO3
• Calcium Carbonate
• NaNO3
• Sodium Nitrate
• FeSO4

15
Molecular compounds

• Example NO2
• Not put together by charge
• Name has to tell how many of each type of atom is
  present
• Consist of nonmetals only

16

• First element listed on periodic table is named
  first
• Second element is named as though it were an
  anion-ends in -ide
• Mono is bad! Not to be used on the first element.
