2 化合物的命名
化合物的命名顺序都是根据化学式从左往右读, 这与中文读法顺序是相反的。表示原子个数时使用 前缀 (1)mono-,(2)di -,(3)tri- ,(4)tetra – ,(5)penta(6)hexa-,(7)hepta-, (8)octa-,(9)nona-,(10)deca-,但 是在不会引起歧义时,这些前缀都尽可能被省去。

(2). Acid radicals for meta-salts (亚酸根 -ite )
Anion’s name = Central element’s root -ite
for example:
ClO2- Chlorite
PO33- Phosphite
IO2- Iodite
Hypoiodite
PO23- Hypophosphite
