Even though the total amount of energy France generates from atomic stations is less than half the amount generated in the United States, no other country relies as heavily on nuclear power.
尽管法国的核能发电量还不及美国的一半,但没有哪个核能利用国家会像法国这样如此严重的依赖这种能源。
The electron's going to come out of that highest occupied atomic orbital, that one that's the highest in energy, because that's going to be the at least amount of energy it needs to eject something.
这个电子应该是从,最高的被占据轨道上出来的,它的能级是最高的,因为这样的话发射出它,只需要消耗最少的能量。
It makes sense that it's going to come out of the highest occupied atomic orbital, because that's going to be the lowest amount of energy that's required to actually eject an electron.
从最高占据轨道上,去掉一个电子是合理的,因为这样是发射一个电子,所损失的最低能量。
