If you looked at heteronuclear molecules and you wanted to compute the bond energy, you might start with the bond energies of the two constituents.
如果你看那些相同电子的分子,你想计算共享能，你也许会从,两个组成部分的总能量。
-
On the other hand, if we have a perfect covalence bond, we have identical equal sharing.
另一方面，如果我们有一个完美的共价键，有相同程度的电子共享。
-
The electrons are not equally shared and the carbon hogs the electrons a little bit more than the hydrogen, so the carbon is electron-rich and the hydrogen is just a little bit electron-deficient.
电子不是平均共享的,碳原子比氢原子吸引电子,更强烈一点点，所以碳原子是富电子,而氢原子是缺电子。
-
For example, H2, N2, they are going to share the electrons uniformly, equally.
比方说，氢气，氮气，他们都无差别的，完全等价地共享电子。
-
But we know that just by this calculation, that we don't have equal sharing.
但是如果通过仅仅计算，我们得不到相同程度的电子共享。
-
And, he asked the question, what if we could share -electrons?
他问了一个问题，如果共享电子会怎么样呢？
-
What if we could share electrons?
如果共享电子会怎么样呢？
-
They all share. Homonuclear species.
共享电子。
-
Last day, Professor Ballinger Lewis introduced you to Lewis who taught us that octet stability could be achieved via electron sharing as an alternative to electron transfer.
昨天，ballinger教授,把我介绍给,他教我们八隅律可以,作为电子传递的方式,可以通过共享电子来实现。
