1·We've got an electron from each of the hydrogens.

然后我们从氢原子那得到了两个电子。

2·What is the energy change going from two atomic hydrogens to one H2?

什么是能量的改变，从两个原子氢到H2分子？

3·Those that are aligned in the place are called equatorial hydrogens.

那些在平面上定向的氢叫做伏平氢。

4·Those that are aligned perpendicular to the plane are called axial hydrogens.

与平面垂直定向的氢叫做直立氢。

5·Those that are aligned perpendicular to the plane are called axial hydrogens .

与平面垂直定向的氢叫做直立氢。

6·Group II: a Group I base oil bombarded with more hydrogens to take more impurities out of it.

第二组：A第一类基础油的轰炸更氢采取更多的杂质了。

7·So we can have four total hydrogens bonding here, - and we can think about how to describe these carbon - carbon bonds.

我们这里一共有四个氢原子成键，我们可以考虑怎么来-，描述碳碳键。

8·Then what you have is a carbon in the middle with three hydrogens around it, and then it can only be bonded to one other thing.

那么你就会有一个碳原子在中心，三个氢原子围绕着它，那么它只能再和一个原子成键。

9·We told you that phosphorous has 5 valence electrons plus 3 from each of the hydrogens, so we have a total of 8 valence electrons.

我告诉过你们磷有5个价电子，另外氢有3个，所以我们一共有8个价电子。

10·The states of active hydrogens, the hindered rotation within molecules and the kinetic phenomena of tautomerism have also been discussed.

还对分子内的受阻旋转、活泼氢状态以及互变异构体的动力学现象作了讨论。
