Ionic Compound Nomenclature v Nomenclature naming and formula

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…)
