Now, from your book as well, this is the pz's of the two atomic orbitals forming the bonding orbital.

现在，也是你们书上，这是两个pz轨道,组成的成键轨道。

So, if we have two atomic orbitals coming together from two different atoms and they combine, what we end up forming is a molecular orbital.

如果我们有两个,不同原子的原子轨道,而且它们组合到一起，我们最后就能得到一个分子轨道。

And there's actually a way that we can make predictions here, and what I'll tell you is molecular orbital theory predicts that h e 2 does not exist because it's not stabilized in terms of forming the molecule.

其实我们有一种办法可以做出预测，我要告诉你们的是分子轨道,理论预测He2不存在,因为它形成分子不稳定。
