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
