Inorganic Nomenclature
1 naming monoatomic metal ions
1.1 use name of metal and add the word 'ion'
1.1.1 sodium metal = sodium ion
1.1.1.1 Na = Na+
2 stock system of naming metal ions
2.1 if a metal ion has more than one possible charge it is indicated by a roman numeral in parentheses following the name
2.1.1 Fe(2+) = iron (II) ion
2.1.2 Fe(3+) = iron (III) ion
2.1.3 U(6+) = uranium (VI) ion
3 naming monoatomic non-metal ions
3.1 monoatomic: species made up of ONE atom
3.1.1 Ne He Li+ Cl-
3.1.2 diatomic: species containing TWO atoms
3.1.3 polyatomic: species containing >1 atom
3.2 take off the original ending and replace with 'ide'
3.2.1 chlorine = chloride
3.2.2 fluorine = fluoride
4 constructing formula of ionic compound given name of compound
4.1 write formula of positive ion first and negative ion next
4.1.1 criss cross the #s in front of the ion charges
4.1.1.1 tidy it up
4.1.1.1.1 if both subscripts can be divided by 2 or 3, do so
4.1.1.1.1.1 omit the superscript charges
4.1.1.1.1.1.1 omit subscripts equal to 1
5 constructing the name of an ionic compound given the formula
5.1 how many possible charges does the first ion have?
5.1.1 one
5.1.1.1 write names of ions one after another
5.1.1.1.1 ZnCl2 = znic chloride
5.1.2 more than one
5.1.2.1 un criss cross subscripts and use as charges.
5.1.2.1.1 if the charge on the negative ion is double/triple the charge calculated by un-criss crossing, double/triple the charges on both positive and negative ions
6 naming hydrates
6.1 add prefix with 'hydrate' after compound
7 naming compounds using prefix-naming system
7.1 generally reserved for binary compounds in which there are two different nonmetals involved
7.2 each compound is made up of two terms, each with a suitable prefix
7.2.1 first word is name of first element with a prefix
7.2.1.1 second word is name of second element with an 'ide' ending and a prefix
