Binary compounds Two elements only End in “ide”Binary ionic-metal and nonmetal Binary molecular – 2 nonmetals
Binary ionic compoundsGroup A metal – name normal Second element changed to an “ide” ending
Binary ionic compoundsCaCl2 Na2O AlBr3 BaS LiI Calcium chloride Sodium oxide Aluminum bromide Barium Sulfide Lithium iodide
Binary molecular coumpoundsAlways two nonmetals First nonmetal name normal Second nonmetal always ends in “ide” Must identify the numbers hanging down (subscripts)
Prefixes 1 Mono- 2 Di- 3 Tri- 4 Tetra- 5 Penta- 6 Hexa – 7 Hepta- 89 10 Mono- Di- Tri- Tetra- Penta- Hexa – Hepta- Octa- Nona- Deca-
Binary molecular compoundsN2O5 P203 SO3 PCl5 Carbon monoxide Dinitrogen pentoxide Diphosphorus trioxide Sulfur trioxide Phosphorus pentachloride
Binary ionic w/group B Still two elements Still a metal and nonmetalFirst element from group B not A Still ends in “ide” Must name metal completely Must know all oxidation states of the metal
