And so the bonding is important as far a carbohydrates go.

因此，就碳水化合物而言，键合至关重要。

So you can break apart the earth and then break apart, you know, atomic molecular bonds.

能将地球分裂，接着还能打破，知道，原子分子间键合。

As pH drops, the substance is more acidic, and essentially there’s more hydrogen ions available for bonding.

随着 pH 值降， 该物质酸性更强， 并且基本上有更多氢离子可用键合。

For example if we have a carbonyl bonded to a Hydroxyl, that, my friends, is a Carboxylic Acid.

例如，如果我们有一个与羟基键合羰基，那，我朋友们， 就一个羧酸。

And all of these differences are simply because of the way their atoms are bonded.

所有这些差异仅仅因为它们原子键合方式。

To figure out how far the ball falls, you need to use the reverse of that connection.

要了解球落多远，您需要 使用反向键合。

They form from overlapping electron clouds or shells, flowing around the nuclei of bonded atoms.

它们由重叠电子云或壳形成， 围绕键合原子原子核流动。

The next simplest alkane contains 2 carbons side by side, each one of them in bonded to 3 hydrogen atoms.

一个最简单烷烃包含 2 个并排碳原子， 每个碳原子都与 3 个氢原子键合。

Those heat-resistant bonds are also one reason that glass made with praseodymium is used in a lot of welders' and glassblowers' masks and goggles.

这些耐热键合也用镨制造玻璃被大量用焊工和玻璃工面具和护目镜原因之一。

Get down to the microscopic level and you've got bonds between all these atoms and molecules, and you're stretching those apart.

深入到微观层面， 现所有这些原子与分子之间都存在着键合，而正在将它们拉开。

And so this is the first video in a set a videos that talk about bonding between molecules and within molecules.

因此, 这一组视频中第一个视频, 讲述了分子之间和分子内键合。

He said the most incredible time was that bond… the evolution of Avogadro's number and the bonding things that happened around 1800, 1900.

他说最令人难以置信时间那个键… … 阿伏加德罗数演变和键合生在 1800 年、1900 年左右。

In order to make a polymer all you need is a molecule that can easily bond to another identical molecule at 2 points.

为了制造聚合物， 您所需要只一种分子， 它可以很容易地在 2 个点上与另一个相同分子键合。

When water freezes, this bonding occurs on repeat, ultimately forming a hexagonal structure due to the angle between hydrogens and oxygen within each molecule.

当水结冰时， 这种键合过程不断重复，最终由每个水分子中氢和氧之间角度， 形成了六边形结构。

There is still going to be bonds between the water molecules, but it is able to kind of wrap around that object right here.

水分子之间依然存在键合，但水能够环绕在物体周围。

According to Pierre Ferragou of New Street Research, a firm of analysts, the Dutch company controls three quarters of the market for high-precision bonding.

根据新街研究公司分析师皮埃尔·费拉古说法，这家荷兰公司掌控着高精度键合市场四分之三。

Okay, now that we have a notation for describing elements and their isotopes, we can talk about the energy associated with a nucleus and its bonds.

好，现在我们有了描述元素及其同位素符号，我们可以讨论与原子核及其键合相关能量。

And whenever you have really strong positivity and really strong negativity, if you have something Really strong on both ends when it is Going to be bonded something else.

无论何时，当拥有极强正电性和极强负电性时，如果两端都有极强性质， 当它与其它物质结合时， 就形成强大键合。

They're easier to pluck off and maybe share with other atoms. Or maybe to give to other atoms, and we'll talk a lot about that when we talk about bonding.

它们更容易被移除，也许可以与其他原子共享。或者也许可以给予其他原子，当我们谈到键合时详细讨论这一点。

And with it’s super-strong bonds, solid metallic hydrogen would also be a great way to store energy, which would make it a better rocket fuel than the fuels we use now, like liquid hydrogen and oxygen.

由其超强键合，固态金属氢也将成为储存能量好方法， 这将使其比我们现在使用液氢和液氧等燃料成为更好火箭燃料。
