✔ 最佳答案
Au在固體時是自由態元素,電荷是0。只有是熔融狀態下才會有離子、電荷的。
而另外兩隻無形成水溶液或熔融狀態下時電荷都是0,是有水中溶解或熔融狀態下才會有離子、電荷的。H+離子,電荷是正1,Cl-離子,電荷是負1,SO4 2-離子,電荷是負2。

When the substance is either solid , liquid, or which is easily ionized of not,if no water present of energy charged, It could not be called ion. After ionization, their balance charge will be spilt, call free ion, cation and anion. Is it ok?

問的是原子团價數,不應用<<電荷>>如金,不離解的就是零電荷.
