Binary Compounds
BINARY COMPOUNDS -Compose of two kinds of atom Polyatomic Ion | Name | OH-1 | hydroxide | SO4-2 | sulfate | PO4-3 | phosphate | NO3-1 | nitrate | CO3-2 | carbonate | HCO3-1 | hydrogen carbonate or bicarbonate | ClO3-1 | chlorate | NH4+1 | ammonium |
TWO NON-METALS - Give the name of the positive ion followed by the negative ion ending with -ide -Greek prefixes are used
CO-carbon monoxide CO2-carbon dioxide NO-nitrogen oxide
PCl5-phosphorous pentachloride N2O5-dinitrogen pentoxide
METAL AND NON-METAL
METALS WITH FIXED OXDATION NUMBER-Give the name of the positive ion followed by the negative ion ending with –ide
Al+3 O-2 =Al2O3 =aluminum oxide
Mg+2 H- =MgH2 =magnesium hydride
METALS WITH VARIABLE OXDATION NUMBER
-ROMAN NUMERAL METHOD -give the name of the positive atom followed by the name of the negative ion ending with –ide. - The only difference here is that we have to specify the charge of the metal ion by using a Roman numeral
Pb+2 O-2 =PbO =Lead (II) oxide
Pb+4 O-2 =PbO2 = Lead (IV) oxide
TERNARY COMPOUNDS -Compose of three or more kinds of atom
-When metals are bonded to polyatomic ions, (consist of two or more atoms with one overall charge) the same rules apply, but you have to learn the names and charges of common polyatomic ions.
Mn+2 SO4-2 =MnSO4 =Manganese (II) sulfate
NH4+ NO3-=NH4NO3 =ammonium nitrate
ACIDS-The hydrogen is written first in the compound and the naming is based on whether the anion (negative ion) is monatomic or polyatomic
Binary Acid-Compose of hydrogen (H+) and a monatomic ion -The first part of the name is the prefix hydro- followed by the name of the negative monatomic ion ending in –ic and the last part of the name is the word acid
H+ Cl- =HCl =hydrochloric acid
H+ S-2 =H2S =hydrosulfuric acid
H+ Br- =HBr =hydrobromic acid
Ternary Acid -Compose of hydrogen (H+) and a polyatomic ion
TWO NON-METALS - Give the name of the positive ion followed by the negative ion ending with -ide -Greek prefixes are used
CO-carbon monoxide CO2-carbon dioxide NO-nitrogen oxide
