例如K2.....兩個K連埋一齊, 2K,兩個K獨立既
咁我想問..點樣睇個K係咪連埋定係獨立分開(我係指做實驗果時睇..唔係文字上..係實質上)

I think you mean the potassium ion in the compound likes K2CO3. Physically those two K are separate potassium cations. How can two positive charges sit next to each other?The numeric ratio of K+ and CO3-- in the ionic crystal is 2 to 1.
