But it didn't matter under those conditions because an electron could then never jump into one of the states of negative energy.
但它在那些情况下并不成为问题，因为一个电子永远不可能跃迁到任何一个负能态之中。
As soon as lanthanum takes that electron, this level rises ever so slightly, and then we jump down here and fill in the lanthanide.
一旦镧得到了电子，这一层就会稍稍上升，然后我们向下填一下镧系元素。
Bohr was able to predict the wave lengths of the light from the makeup of the atom, and the jump from electron orbit to electron orbit.
玻尔根据原子的结构，和在电子轨道间的跳跃情况，就能预见光的波长。
Hit it with just the right amount of energy, and it will absorb it, and the electron will jump up to a higher energy level.
适量的能量撞击电子时，电子将吸收能量并跳跃至高能级轨道。
I can see many electron cloud suddenly vanish on the originally track, then jump to the higher energy level track.
我可以看到很多电子云突然间在自己原本的轨道上消失，然后跃迁到更高能级的轨道上。
UV is an electromagnetic wave, the electron atoms jump from the high-energy bands at low energy band, will release excess energy in electromagnetic waves.
紫外线是电磁波的一种，原子中的电子从高能阶跳到低能阶时，会把多余能量以电磁波释出。
