Naming of Cations
-monoatomic cations bear same name as their elements (ex. Na+ = sodium ions, Ca(2+) = calcium ion)
-some metals can form more than one type of cation (ex. Cu+ = copper(I) ion, Cu(2+) = copper(II) ion)
-Polyatomic cations (NH4(+) = ammonium ion, H3O(+) = hydronium ion)
Naming of Anions
-simple anions end in -ide (Cl- = chloride ion, O(2-) = oxide ion, N(3-) = nitride ion)
-Polyatomic anions end in -ite or -ate (SO3(2-) = sulfite ion, ClO(-) = hypochlorite ion)
Inorganic Acids
compounds containing H+ and a simple anion (Binary acids, ex. HCl, H2S) or polyatomic anion (Oxo acids, ex. HNO3, H2SO4)
Naming Ionic Compounds
-name the cation, then name the anion (ex. CaCl2 = calcium chloride, NH4NO3 = ammonium nitrate)
Naming Covalent Compounds
-name the electropositive element, then name the electronegative element like an anion
-electronegative element ends in -ide
-use prefixes to indicate the number of each kind of atom in a molecule (CO2 = carbon dioxide, SO3 = sulfur trioxide)
Ammonia
NH3
Naming Inorganic acids
-names of acids are based on the names of the anions in the acids
-(-ide = hydro-…-ic acid) (ex. HCl = hydrochloric acid)
-(-ate = -ic acid) (ex. HNO3 = nitric acid)
-(-ite = -ous acid) (ex. HNO2 = nitrous acid)
Naming Inorganic compounds flowchart
-Does it carry charges? (If yes, name it as ion)
-Is it an acid (if yes, name the acid)
-Is it ionic or covalent?
Superoxide ion
O2(-)
Peroxide ion
O2(2-)
Hydrate
compounds in which water molecules (H2O) are bound to another element/compound
(ex. CuSO4 x 5H2O = Copper(II) sulfate pentahydrate)
Hygroscopic substances
absorb moisture from air to form hydrate, usually appear sticky or wet
Anhydride
a substance without water
Element order of Covalent Compound
1st: central element
2nd: peripheral element
