Ionic Compound Nomenclature v. Nomenclature – naming and formula writing of chemical compounds
Ionic Nomenclature § Ionic bonding occurs between… § a metal & a non-metal § To name an ionic compound: § name the metal § name the non-metal, adding an –ide ending § name the cation, name the anion
Ionic Nomenclature § For example… Ca. Cl 2 § forms from: § the calcium ion, Ca 2+ § and the chloride ion, Cl§ So, the name of Ca. Cl 2 is calcium chloride.
Ionic Nomenclature 1. Mg. O magnesium oxide 2. Al 2 O 3 aluminum oxide 3. Rb 3 P rubidium phosphide
Ionic Nomenclature § To write formulas for an ionic compound, determine what charge is on the metal ion and what charge is on the non-metal ion. § Then, determine the formula, so that the compound is neutral (the ‘criss-cross’ method may be useful in determining the formula)
Ionic Nomenclature § For example… magnesium bromide is made up of magnesium ions (Mg 2+), and bromide ions (Br-) § Mg 2+ Br§ So, the formula is Mg. Br 2
Ionic Nomenclature 1. sodium chloride 2. barium fluoride 3. potassium sulfide 4. magnesium phosphide 5. calcium oxide (try some more…)
Type II Ionic Nomenclature What is the name of: Fe. S? Fe 2 S 3? Au. F 3?
Type II Cations Cu+ Cu 2+ Fe 3+ Sn 2+ Sn 4+ Cr 2+ Cr 3+ Mn 2+ Mn 3+ Hg 22+ Hg 2+ Pb 4+ Co 2+ Co 3+ Au 3+ Ni 2+ Ni 3+ copper(I) copper(II) iron(III) tin(IV) chromium(III) manganese(III) mercury(II) lead(IV) cobalt(III) gold(III) nickel(III) cuprous cupric ferrous ferric stannous stannic chromous chromic manganous manganic mercurous mercuric plumbous plumbic cobaltous cobaltic aurous auric nickelous nickelic
Type II Ionic Nomenclature What is the formula of: copper(II) bromide? plumbous chloride? lead(IV) oxide? chromium(III) sulfide? manganic selenide?
