nucleus shielded 屏蔽核
They're less shielded because they're closer to the nucleus, they feel a greater z effective.
它们受到少的屏蔽,因为它们离原子核更近,它们感觉到一个更大的有效电荷量。
The outermost electron is shielded from the nucleus.
细胞中最重要的部分是细胞核。
The outermost electron is shielded from the nucleus.
原子核对最外层电子的作用受到屏蔽。
They're less shielded because they're closer to the nucleus, they feel a greater z effective.
它们受到少的屏蔽,因为它们离原子核更近,它们感觉到一个更大的有效电荷量。
A kind of consequence of this is if we're thinking about a multi-electron atom, which we'll get to in a minute where electrons can shield each other from the pull of the nucleus, we're going to say that the electrons in the s orbitals are actually the least shielded.
这样的一个后果就是,如果我们考虑一个多电子原子,我们等会就会讨论到它,电子会互相,屏蔽原子核的吸引,我们说s轨道电子,更不容易被屏蔽。
