"WebBeryllium and magnesium do not give colour to flame whereas other alkaline earth metals do so. Why? Solution When an alkaline earth metal is heated, the valence electrons get excited to a higher energy level. When this excited electron comes back to its lower energy level, it radiates energy, which belongs to the visible region. " - Flame color of beryllium
