当测度不是全相加的时,应考虑将它们分成其原子元素。
When they are not, you should consider breaking them down into their atomic elements.
早期版本的一些元素原子序数不正确。
Early versions had the incorrect atomic number for some elements.
仅仅5年后,一种具有适当原子质量的元素被分离出来,并被发现者命名为镓。
Just five years later an element with the proper atomic mass was isolated and named gallium by its discoverer.
And, at the other extreme, we have elements with very high value, elements with high average valence electron energy.
另外,在另一端,我们有原子序数较大的元素,这些元素有着较高的平均化合价和电子能。
Now, chlorine I have to do a little bit more heavy lifting here because chlorine starts as a diatomic molecule.
现在,对于氯,我将会做更多的说明,因为氯元素起初存在于双原子分子中。
So, that's actually the electron configuration we have when we're talking about copper and some other exceptions in the periodic table that you're going to be looking at.
因此,这才是铜原子真正的电子排布,而且我们在元素周期表中,会看到与铜原子类似的,其他例外的情况。
