Chapter 7 Chemistry Nomenclature

Binary Compounds are composed of two elements.

Binary Ionic Compounds are named by combining the names of the positive and negative ions.

Ions formed from a single atom.

Naming system

An ionic compound composed of a cation and the anion from an acid is often referred to as a salt.

Polyatomic ions that contain oxygen.

Metal/Nonmetal; Example- MgCl₂ Magnesium Chloride

Are molecular compounds composed solely of carbon and hydrogen.

Consists of a lattice of positive and negative ions held together by mutual attraction.

• This system uses Roman numerals to indicate an ion's charge. The numeral is enclosed in parentheses and placed immediately after the metal name.
• CuCl₂  copper(ll) chloride.

• The old system of naming molecular compounds is based on the use of prefixes.
• CCL₄ -Carbon Tetrachloride

• Similar to naming molecular compounds.
• SiC- Silicon Carbide
• SiO₂- Silicon Dioxide

Are acids that consists of two elements, usually hydrogen and one of the halogens.

Are acids that contain hydrogen, oxygen, and a third element (usually a nonmetal).

• Hydrogen: +1
• Oxygen: -2
• Halogens: -1

• Metal/Nonmetal; a neutral exchange of e^- 
• Example: FeO Iron(ll) Oxide
• Example: Sr(OH)₂ Strontium Hydroixide

• Salt w/water molecules; name= salt x #Hydrate
• Example:PbO₂  Lead(lV) Oxide Hexahydrate

• Nonmetal/Nometal; covalent bonds share e^- 
• Name= #element #-ide
• Example:P₂O₅ Diphoshorous Pentaoxide

• Single bonds between C: ane
• Double bonds between C: ene
• Alcohol- OH

• 1-methyl (MeEatPeanutButter)
• 2-ethyl
• 3.propal
• 4.butly 

• Methane
• Meth- One Carbon Ane- Single Bonds (Carbon has four bonding sites so four single bonds)

• H⁺       -ide    = Hydro__ic Acid (NO O!!!)
• H⁺       -ate   = ____ic Acid
• H⁺      -ite    = ____ous Acid

• Example: Phosphoric Acid H₃PO₄
• Example: HNO₂ Nitrous Acid
• Example: H₂S Hydrosulfuric Acid

Can be refered to as a moleular mass.

Of any molecule, formula unit, or ion is the sum of the average atomic masses of all atoms represented in its formula.

Molar mass and formula mass are both numerically equal.

Consists of the symbols for the elements combined in a compound, with subscripts showing the smallest whole number ratio of different atoms in the compound.
