Question

The most correct reason for the colour of the flame due to alkali metal ions is (A) presence of single valence electron (B) excitation of valence electron (C) emission of radiation in visible region when electron come back to the ground state energy level (D) None of the above

Tardigrade Admin · Accepted Answer

The alkali metals and their salts impart colour to an oxidising flame. This is due to emission of radiation in visible region when the excited electron come back to the ground state energy level.
