So, why don't you go ahead and tell me, keeping that in mind, which atom in terms of h c or n would you expect to be in the center of hydrogen cyanide?

那么，请大家来告诉我，并且记住它，你认为氢，碳和氮中哪个原子,应该在氰化氢的中间呢？

In other words if you say, how many vibrations are there in the lattice, well if there are N atoms, each atom in the gas phase would have three degrees of freedom.

换句话说，你会问经各种有多少振动，如果有N个原子，气相中的每个原子有,3个自由度。

So, that also tells us that the n minus ion is less stable than the neutral atom itself.

而且，这还告诉我们,负一价的氮离子不如中性氮原子稳定。
