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？

H We've been talking about atomic hydrogen, h.

我们讨论的原子氢。

Ionized by energetic starlight, a hydrogen atom emits the characteristic red H-alpha light as its single electron is recaptured and transitions to lower energy states.

氢原子被高能的恒星光离子化之后，在它的单个电子重新被捕获并跃迁到低能级上时会放出典型的红色h - alpha光。

H And, by the way, if you do this for the hydrogen, H it ought to come out the same.

顺便说一句，如果是，或者如果是。

Well, we would have to H+ have one of these hydrogen atoms go to an H plus, * plus an electron, right? **H --> H+ + e-** So, now we have a hydrogen ion here.

我们先要让,一个氢原子变成氢离子，加上一个电子，对么*,我们现在有一个氢离子了。

Their H2O turns into H (ie, hydrogen atoms) and OH (so-called hydroxyl molecules).

ECONOMIST: Creative destruction

So by building up the concentration of ammonium ions inside its retaining membrane, H. pylori is able to fend off the destructive attentions of the hydrogen ions in stomach acid and thus live free from competition by less hardy germs.
