甚麼是ployatomic ions？
仲有我想問下
OH￣ ，NO3￣ ，NO2￣
呢D係點砌埋架
點解non-metal可以同non-metal form ionic bond既

✔ 最佳答案
由多於一個原子所組成的離子稱為ployatomic ions，例如 (SO4)2-。OH￣ 是 (O-H)￣，其中O和H之間有共價鍵。
同樣道理，NO3￣ ，NO2￣ 之中也是N和O之間有共價鍵。
這種情況是non-metal之間有共價鍵而不是ionic bond。

ployatomic ions means an ion contain more than one atom,e.g.:OH￣ ;
OH￣ ，NO3￣ ，NO2￣,the attraction between each atom is covalent bond,because they are non-metal;
non-metal and non-metal cannot form ionic bond,only form covalent bond
OH￣ ，NO3￣ ，NO2￣,the attraction between each atom is covalent bond,because they are non-metal;
non-metal and non-metal cannot form ionic bond,only form covalent bond
