Flame colouration of lithium
WebFlame colouration : Except Be and Mg, other members impart characteristic colours when their salts are introduced in the flame. Hydration energy : The M 2+ ions of alkaline earth metals are extensively hydrated to form [M(H 2 O)x] 2+ ions and during hydration a huge amount of energy called hydration energy is released. M 2+ + xH 2 O [M(H 2 O)x ... WebWhen these electrons return to their ground states, they emit extra energy in form of radiations which fall in the visible region thereby imparting a characteristic colour to the …
