Document Summary
(cid:862)ate(cid:863)/(cid:863)ite(cid:863)- polyatomic ion involved- most anions; only cation- ammonia. Cation main groups (+1) group one metals w/out hydrogen (+2) group two metals (+3) group 3- only al, ga, and in. Anion main groups: no noble gases (-1) f-i (-2) o-te (-3) n and p only. Transition metals: the only two that only have an unchanging charge are zinc (+2) and silver (+1, all others have variating charges. Examples (all ionic): bacl2- barium chloride (only one charge involved, crcl3- chromium (iii) chloride (use roman numerals when more than one charge involved, pbs- lead (ii) sulfide, fe2o3- iron (iii) oxide. Mono- never used on first element, only on second: ex: co- carbon monoxide. Naming binary molecular compounds: pcl3- phosphorus trichloride, n2o3-dinitrogen trioxide, p4o7- tetraphosphorus heptoxide, brf3- bromine triflouride. Naming compounds with polyatomic ions: lino3- lithium nitrate, khso4- potassium bisulfate, cuco3- copper (ii) carbonate, fe(clo4)3- iron (iii) perchlorate. Hcl (aq) hydrochloric acid (aqueous- can be dissolved in water)
