A lilac-coloured flame is produced on heating.
Open in App
Solution
The correct option is A Potassium in a flame
Potassium on heating produced lilac-colured flame because on heating, an atom entities its electrons and they jump to higher energy levels. When the electron return to lower energy levels, they emit energy in the form of light. The colour produced on heating depends upon wavelength of emitted light.
