1- names always start with the metal.
2- if the metal is a transition element of Lead Pb or Tin Sn, its valency should be specify according to Stocks system.
3- the anions could be simple ions, like Cl- , O2-,
N3-
4- the anion could also be an oxygenated anion like CO32-,
NO3-, SO42-
5- some special anions to remember, Cyanide CN-, permenganate MnO4-, thiocyante SCN-
