可汗学院:生物化学 And then it starts filling up the p orbitals. 然后它开始填充 p 轨道。 可汗学院:生物化学 So that's where the last three electrons go into the p orbital. 这就是最后三个电子进入 p 轨道的地方。 Crash Course 综合篇 But, in the second shell, we have an s orbital and 3 p orbitals. 但是,在第二层中, 我们有一个 s 轨道和 3 p 轨道。 Crash Course 综合篇 The p orbitals, if they were all by themselves, look like this. p轨道,如果它们都是单独的, 看起来像这样。 Crash Course 综合篇 The s and the p orbitals can merge into hybrid sp orbitals. s 和 p 轨道可以合并成混合 sp 轨道。 可汗学院:生物化学 These over here are going to fill the p orbitals. 这里的这些将填充 p 轨道。 可汗学院:生物化学 And notice the p orbitals have something, p sub z, p sub x, p sub y. 注意 p 轨道有一些东西,p sub z, p sub x, p sub y。 Crash Course 综合篇 This creates a sheet with a hexagonal structure and with one unhybridized P orbital left on each atom. 这将创建一个具有六边形结构的薄片, 每个原子上都有一个未杂化的 P 轨道。 Crash Course 综合篇 But s and p orbitals can hybridize in other ways as well. 但是 s 和 p 轨道也可以以其他方式杂交。 Crash Course 综合篇 So, s orbitals, very simple, spherical, p orbitals a little bit weirder, d and f orbitals, so crazy. 所以,s 轨道,非常简单,球形,p 轨道有点奇怪, d 和 f 轨道, 太疯狂了。 化学 Crash Course A second and weirder bond forms, this one from the unhybridized p orbital sticking out above and below the nucleus. 第二个更奇怪的键形成,这个键来自未杂化的 p 轨道,在原子核上方和下方突出。 Crash Course 综合篇 When the s orbital hybridizes with all 3 p orbitals it's called sp3 hybridization and it forms a tetrahedral shape. 当 s 轨道与所有 3 p 轨道杂化时, 称为 sp3 杂化,并形成四面体形状。 可汗学院:生物化学 So the question is what would this look like if we just wanted to visualize this orbital right here, the p orbitals? 所以问题是,如果我们只想在这里可视化这个轨道 p 轨道,它会是什么样子? Crash Course 综合篇 After we fill the first and second s orbitals, we move on to filling the p orbital. 在我们填充第一个和第二个 s 轨道后, 我们继续填充 p 轨道。 Crash Course 综合篇 And, yes, sp orbitals, where the s only hybridizes with one p orbital, are also all over the place. 而且,是的,sp 轨道, 其中 s 只与一个 p 轨道杂化, 也到处都是。 化学 Crash Course Each of those can contain 2 electrons for a total of 8 with 2 in the s orbital and 6 in the 3 p orbitals. 其中每一个都可以包含 2 个电子,总共 8 个电子,其中 2 个在 s 轨道中,6 个在 3 p 轨道中。 Crash Course 综合篇 It only hybridizes 2 p orbitals with the s orbital, forming 3 sp2 hybridized orbitals with an unhybridized p orbital sticking up from the center. 它仅将 2 个 p 轨道与 s 轨道杂化, 形成 3 个 sp2 杂化轨道,其中未杂化的 p 轨道从中心伸出。 Crash Course 综合篇 The carbon is going to have 2 double bonds, so it has to have 2 un-hybridized p orbitals and one sp hybridized orbital. 碳将具有 2 个双键,因此它必须具有 2 个未杂化的 p 轨道和一个 sp 杂化轨道。 化学 Crash Course But, when you actually stick them around an atom, the s and p orbitals start to interact with each other, doing their best not to overlap and changing each other. 但是,当你真的把它们粘在一个原子周围时,s 和 p 轨道开始相互作用, 尽量不重叠和相互改变。 Crash Course 综合篇 The oxygens are going to have one double bond, so they need to set up as sp2 hybridized with one un-hybridized p orbital, for the double bonding. 氧将具有一个双键,因此它们需要设置为 sp2 与一个未杂化的 p 轨道杂化, 以形成双键。 |
