Chem Chapter 2 Part 2
polyatomic ions that end in ______________ have more ____________
-ate oxygen
the anion is named by adding the suffix __________ to the root of the nonmetal name
-ide
greek prefixes for naming molecular compounds (1-10)
1--mono 2--di 3--tri 4--tetra 5--penta 6--hexa 7--hepta 8--octo 9--nona 10--deca
prefix - root - suffix of polyatomic atoms with 3 oxygen
N/A - root - ate
prefix - root - suffix of polyatomic atoms with 2 oxygen
N/A - root - ite
acid suffixes
anion: -ate acid: -ic acid anion: -ite acid: -ous acid
binary acid
binary acid solutions form when certain gaseous compounds dissolve in water
naming ionic compounds
chemical formula --> name if the metal has more than 1 possible charge, you MUST specify the charge in the name identify polyatomic ions name --> formula charge MUST balance treat polyatomic ions as one charged units
ionic compounds
composed of 2 types of ions: positive and negative the total charge must equal 0 to give a neutral compound
monoatomic ions
derived from a single atom
metals with only 1 possible charge
group 1 group 2 Al Ag Cd Zn
prefix - root - suffix of polyatomic atoms with 1 oxygen
hypo - root - ite
naming acids (H + nonmetals)
if the anion = nonmetal hydro + nonmetal + ic + acid if the anion = polyatomic polyatomic anion + new suffix + acid
naming ionic compounds if the metal has more than 1 possible charge
metal + (charge in Roman numerals) + nonmetal + ide OR metal + (charge in Roman numerals) + polyatomic ion
naming ionic compounds if the metal has 1 possible charge
metal + nonmetal + ide OR metal + polyatomic ion
naming molecular compounds
only for binary compounds of 2 nonmetal elements use prefixes to indicate the number of atoms of each element add an -ide suffix mono is usually dropped from the first element the first element in the formula retains its name the name of the second element is change to end in -ide a greek prefix is used to indicate the number of atoms of each element present
oxoacid
oxoacid names are similar to those of the oxoanions, except for 2 suffix changes the oxoanion prefixes hypo- and per- are retained
prefix - root - suffix of polyatomic atoms with 4 oxygen
per - root- ate
naming binary ionic compounds (metal forms only 1 ion)
the cation is named first and the anion second the name of the cation is the name of the metal the name of the anion has the suffix -ide added to the root of the nonmetal name no prefixes are used when naming ionic compounds
naming binary ionic compounds (metal forms more than 1 ion)
the cation is named first and the anion second the name of the cation is the name of the metal with a roman numeral in ( ) following the metal name to indicate the ionic charge the name of the anion has the suffix -ide added to the root of the nonmetal name no prefixes are used when naming ionic compounds
the name of the cation is _____________ the name of the metal many metal names end in _________________
the same as -ium
