1·The energy for single hydrogen atom is negative 1312 kilojoules per mole.
单个氢原子的能量是 -1312 千焦每摩尔。
2·So let's say, for example, in a hydrogen atom.
比如说，在氢原子里。
3·So today, we're going to start talking about the hydrogen atom.
今天我们将谈到氢原子。
4·We will consider this Zeeman effect for the hydrogen atom.
我们将对氢原子考虑此塞曼效应。
5·All right. So today we're going to finish up our discussion of the hydrogen atom.
好，今天我们要结束，关于氢原子问题的讨论。
6·The hydrogen atom is lighter and simpler than the atoms of any other elements.
氢原子较之其他任何元素的原子的重量都轻，结构都简单。
7·If one hydroxyl steals other's hydrogen atom, it will turn into water molecule.
如果其中一个羟基抢断对方的氢原子，它会变成水分子。
8·Zap a hydrogen atom and it will resonate at a particular rate: 1420 megahertz (MHz).
轰击氢原子可以与某一特定的频率产生共鸣: 1420兆赫。
9·The univalent organic radical C6H5, derived from benzene by removal of one hydrogen atom.
苯基单价有机基因，c6h5，通过去掉一个氢原子而从苯中提炼出来。
10·So if I tell you that the energy for single hydrogen atom is negative 13 12 kilojoules per mole.
如果我告诉大家单个氢原子的能量，是负的，1312，千焦每摩尔。
1·The energy for single hydrogen atom is negative 1312 kilojoules per mole.
单个氢原子的能量是 -1312 千焦每摩尔。
2·Since the hydrogen atom is one of the best-measured systems in all of science, this opens the door to a series of experiments testing just how similar matter and antimatter really are.
由于氢原子是所有科学体系中人类了解最透彻的系统之一，这就为测试物质与反物质到底有多少相似之处而进行一系列的试验开启了大门。
3·But, in fact, we can also talk about the ionization energy of different states of the hydrogen atom or of any atom.
但实际上我们也可以讨论氢原子，或者其它任何原子的其它能级的电离能。
4·Zap a hydrogen atom and it will resonate at a particular rate: 1420 megahertz (MHz).
轰击氢原子可以与某一特定的频率产生共鸣: 1420兆赫。
5·In terms of where different atoms are in a molecule, if you have a hydrogen atom or a fluorine atom, you can pretty much guarantee they're always going to be terminal atoms.
对于不同原子在分子中的位置，如果你有一个氢原子或者一个氟原子，那你基本可以保证，它们总是最末端的原子。
