Binary Compounds Metals (fixed oxidation) + Nonmetals

Binary Compounds Binary compounds that contain a metal of fixed oxidation number (group 1, group 2, Al, Zn, Ag, etc. ), and a non-metal. To name these compounds, give the name of metal followed by the name of the non-metal, with the ending replaced by the suffix –ide. Examples: Na. Cl sodium chloride (Na 1+ Cl 1 -) Ca. S calcium sulfide (Ca 2+ S 2 -) Al. I 3 aluminum iodide (Al 3+ I 1 -)
