chemistry: colours of ions
What are the colours of different ions?
e.g. Cu2+ is bluish green

Na+, K+, Cu2+, Ca2+ are four very special metal, 4 of which will burns with a coloured flame. (Only this 4)
The information above is the colour shown when the ions dissolve in water.Source(s): Noted: 只有過渡元素的 ions 才有可能有色
