electron density

基本解釋

The spatial distribution of that image represents the electron density around the atom.
圖像的空間分佈就代表了原子周圍的電子密度。
And we know that it's electron density between the nuclei that holds two atoms together in a bond.
我們知道是兩個(gè)原子核之間的,電子密度保持兩個(gè)原子在一起成鍵的。
Because we know as we go to infinity, even though the density gets smaller and smaller and smaller, we still have electron density very far away from the nucleus.
因爲(wèi)我們知道即使到了無(wú)窮遠(yuǎn)処，盡琯電子密度會(huì)變得非常非常非常小，但我們?nèi)匀挥幸欢ǖ碾娮用芏?，無(wú)論離原子核多遠(yuǎn)。

Sometimes we have a very electronegative atom that's going to take more of its equal share of electron density.
有時(shí)候我們會(huì)有一個(gè)電負(fù)性很高的原子,它將會(huì)獲取更多的共用電子密度。

Great. Yup, it's going to be an electron acceptor, it wants to accept electrons, it wants to accept electron density.
很好，沒(méi)錯(cuò)，它將是一個(gè)電子的受主，它想要接收電子，接收電子密度。

So you can see that this is non-bonding, this is even worse than non-bonding, it's anti-bonding, because we're actually getting rid of electron density between the two nuclei.
所以你可以看到這是不成鍵的，它甚至比不成鍵還糟糕，它是反鍵，因爲(wèi)我們實(shí)際上是去掉了,兩個(gè)原子核之間的電子。
