原声例句
Crash Course 综合篇 Which so friction-less because of fluorine's extreme electronegativity. 由于氟的极端电负性, 因此摩擦较小。 Awesome Nature An atom's relative greed for electrons is called its electronegativity. 一个原子对于电子的相对贪欲叫做负电性。 可汗学院:生物化学 And the intermolecular force, in turn, depends on the electronegativity. 而分子间力又取决于电负性。 可汗学院:生物化学 And there's a very small difference in electronegativity between the carbon and the hydrogen. 碳和氢之间的电负性差异非常小。 化学 Crash Course Alcohols and aldehydes have a lot of similar properties because of the electronegativity of the oxygen. 。 由于氧的电负性, 醇和醛具有许多相似的性质。 可汗学院:生物化学 But they have a very high electronegativity. 但是它们具有非常高的电负性。 可汗学院:生物化学 And to think about, to just think about electronegativity makes it a little bit more tangible. 想想,只要想想电负性就会让它变得更加有形。 Crash Course 综合篇 That, along with the difference in electronegativities of oxygen and hydrogen, leads to the polarity of water and the existence of life. 那, 连同氧和氢的电负性差异,导致了水的极性和生命的存在。 可汗学院:生物化学 And especially when you start going into oxidation numbers and things like that, electronegativity will tell you a lot. 特别是当你开始研究氧化数之类的东西时,电负性会告诉你很多。 可汗学院:生物化学 And that allows us to compare different elements in terms of their electronegativities. 这使我们能够根据电负性比较不同的元素。 可汗学院:生物化学 Let's look at the differences in electronegativity between sodium and chlorine. 让我们看看钠和氯之间的电负性差异。 可汗学院:生物化学 So Linus Pauling actually calculated electronegativity values for the elements and put them into the table. 所以 Linus Pauling 实际上计算了元素的电负性值并将它们放入表中。 可汗学院:生物化学 For example, we are concerned with carbon, which has an electronegativity value of 2.5. 例如,我们关注的是碳,它的电负性值为 2.5。 可汗学院:生物化学 And we're going to compare that to oxygen, which has an electronegativity value of 3.5. 我们将把它与电负性值为 3.5 的氧气进行比较。 化学 Crash Course Electronegativity increases from left to right because there are more protons in the atoms, and more protons means more boys in the band. 电负性从左到右增加,因为原子中有更多的质子,更多的质子意味着乐队中有更多的男孩。 可汗学院:生物化学 So this trend right here, when you go from the left to the right, your electronegativity, let me write this, your getting more electronegative. 所以这个趋势就在这里,当你从左到右时,你的电负性,让我写下这个,你的电负性越来越强。 化学 Crash Course Now in extreme cases, like if the electronegativity is greater than 1.6, then we end up with two ions in the same molecule. 现在在极端情况下,比如如果电负性大于 1.6,那么我们最终会在同一个分子中得到两个离子。 可汗学院:生物化学 I'm going to compare carbon to oxygen in terms of the electronegativity. 我将在电负性方面比较碳和氧。 可汗学院:生物化学 And then in blue, it gives us the Pauling scale for electronegativity. 然后在蓝色中,它为我们提供了电负性的鲍林标度。 可汗学院:生物化学 So that's an electronegativity difference of 1.4. 所以这是 1.4 的电负性差异。

电负性 Electronegativity(重定向自Electronegativities)
电负性(英语:electron negativity,简写EN),也译作离子性、负电性及阴电性,是综合考虑了电离能和电子亲合能,首先由莱纳斯·鲍林于1932年提出。它以一组数值的相对大小表示元素原子在分子中对成键电子的吸引能力,称为相对电负性,简称电负性。元素电负性数值越大,原子在形成化学键时对成键电子的吸引力越强。

Electronegativity 电负性(重定向自Electronegativities)
![]() ![]() ![]() ![]() Electronegativity, symbol χ, is a chemical property that describes the tendency of an atom or a functional group to attract electrons (or electron density) towards itself. An atom's electronegativity is affected by both its atomic number and the distance at which its valence electrons reside from the charged nucleus. The higher the associated electronegativity number, the more an element or compound attracts electrons towards it. |
