Cations NH 4 ammonium H 3 O hydronium 2) Naming ionic compounds . a) [Main group metal (1A, 2A, aluminum (3A) metals)] + [main group nonmetal]: name of metal + name of nonmetal + ide Example: CaF 2 is calcium fluoride, Li 3 P is lithium phosphide, Al 2 S 3 is aluminum sulfide b) [Transition group metal (or group 4A metal, or Tl)] + [main group nonmetal]: name of metal (charge of metal) + name of nonmetal + ide Example: Cu 2 O is copper (I) oxide, CuO is copper (II) oxide, SnF 2 is tin (II) fluoride c) Cation group (NH 4 + is the only common cation group, and is called ammonium ion) Example: NH 4 Br is ammonium bromide d) Anion group PO 4 3- is phosphate ion C 2 H 3 O 2 - is acetate ion CO 3 2- is carbonate ion CN - is cyanide ion SO 4 2- is sulfate ion OH - is hydroxide ion ClO 3 - is chlorate ion IO 3 - is iodate ion BrO 3 - is bromate ion NO 3 - is nitrate ion +1 oxygen changes the name to per ________ ate -1 oxygen changes the name to ________ite -2 oxygen changes the name to hypo ________ ite HPO 4 2- is hydrogen phosphate ion HCO 3 - is hydrogen carbonate ion HSO 4 - is hydrogen sulfate ion H 2 PO 4 - is dihydrogen phosphate ion 3) Naming acids . a) Binary acids (hydrogen + nonmetal) hydro + nonmetal + ic acid b) Ternary acids (hydrogen + oxygen + nonmetal) hypo ________ ion becomes hypo ________ ous acid ________ ite ion becomes ________ ous acid ________ ate ion becomes ________ ic acid per ________ ate ion becomes per ________ ic acid 4) Naming binary molecular compounds (compounds are usually two nonmetals)a) Left or lower element is named first, second element is given an ide ending, prefix is used to indicate the number of atoms per molecule (but the prefix mono is never used for the first element) mono = 1tri = 3 penta = 5 hepta = 7 di = 2 tetra = 4 hexa = 6 octa = 8 b) A few have common names: H 2 O is water, NH 3 is ammonia, CH 4 is methane. c) If a binary molecular compound forms an acid when added to water the naming of the compound depends on whether it is in the gas phase or aqueous phase Length 1km=1000 meters, .6214mi, 1mile=1.6099km 1meter=100cm, 1.094yds, 1000mm, 39.37in, 1yd=.9133m 1cm= .01m, .3937in, 1inch=2.54cm, 1ft=.3048m km/hr divide by 3.6m/s 5280ft = 1mi
