PROFESSOR: No. So, compared to the atoms, it should be somewhat the same energy, we shouldn't get any extra stabilization from forming the molecule.
不会,所以和原子相比,它的能量相同,形成分子并不会带来额外的稳定性。
What we're going to do in forming a molecule is just bring these two orbitals close together such that now we have their nucleus, the two nuclei, at a distance apart that's equal to the bond length.
我们在形成一个分子时要做的就是,把这两个轨道放到一起,这样我们有他们的原子核,两个原子核,它们之间的距离为键长。
And where we had left off was we were going to start one example of thinking about now where we have a heteronuclear diatomic molecules, so two different atoms in terms of forming the molecule.
我们还剩下一个,异核双原子分子的例子没讲,这里组成分子的原子,是不同的。
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。
