These flame ... WebJun 4, 2014 · Generally the colour of flame of alkaline metals are due to the reason that electrons are excited to higher energy levels and when they drop back to the ground state, energy is emitted in the form of visible light. Since the electrons in beryllium and magnesium are too strongly bound it cannot get excited by flame.
