I was told at school that when a hydrogen electron gains heat energy enough to excite it shifts to a higher energy level, then after a very small period it falls back to its ground energy level, that means all the energy it gains should be lost, but if that is true since hydrogen has an electron at the first energy level, why when it's excited it doesn't have to fall back to its original energy level, but instead it falls to any Lower energy level producing different series of spectrum, thanks in advance guys !
