Kurzgesagt 科普动画 The rest, a sphere of influence about as large as the Eiffel tower from your perspective, is filled with an electron cloud. 剩下的会是以一个在你看来和艾菲尔铁塔同高的影响球体存在,里头充满了电子云。 Crash Course 综合篇 They form from overlapping electron clouds or shells, flowing around the nuclei of bonded atoms. 它们由重叠的电子云或壳形成, 围绕键合原子的原子核流动。 Crash Course Physics 速成课物理 You know those electron clouds you'll sometimes see in models of atoms? 你有时知道你身上的那些电子云 在原子模型中看到了吗? SciShow - Chemistry The area where you might find it if you tried to measure it is called the electron cloud. 如果你试图测量它,你可能会发现它的区域称为电子云。 SciShow - Chemistry But if you’re studying chemical bonds, you might need the electron cloud model to know where the electrons are. 但如果你正在研究化学键,你可能需要电子云模型来了解电子的位置。 万物简史 The " shell" of an atom isn't some hard shiny casing, as illustrations sometimes encourage us to suppose, but simply the outermost of these fuzzy electron clouds. 原子的壳并不是某种坚硬而光滑的外皮,就像许多插图有时候怂恿我们去想像的那样,而只是这种绒毛状的电子云的最外层。 SciShow - Chemistry So, the electron cloud model is the most up-to-date model of an atom, and it’s used by scientists around the world. 因此,电子云模型是最新的原子模型,全世界的科学家都在使用它。 化学 Crash Course They form from overlapping electron clouds or shells, flowing around the nuclei of bonded atoms. If you really get down there and understand what they look like, they're like lumpy, clumpy globs of probable electron locations. 它们由重叠的电子云或壳形成,围绕键合原子的原子核流动。 如果你真的深入了解它们的样子, 它们就像可能是电子位置的块状团块。

原子轨道 Atomic orbital(重定向自Electron cloud)
![]() ![]() ![]() ![]() 原子轨域(德语:atomorbital;英语:atomic orbital),又称轨态,是以数学函数描述原子中电子似波行为。此波函数可用来计算在原子核外的特定空间中,找到原子中电子的机率,并指出电子在三维空间中的可能位置。「轨域」便是指在波函数界定下,电子在原子核外空间出现机率较大的区域。具体而言,原子轨域是在环绕着一个原子的许多电子(电子云)中,个别电子可能的量子态,并以轨域波函数描述。 现今普遍公认的原子结构是波耳氢原子模型:电子像行星,绕着原子核(太阳)运行。然而,电子不能被视为形状固定的固体粒子,原子轨域也不像行星的椭圆形轨道。更精确的比喻应是,大范围且形状特殊的「大气」(电子),分布于极小的星球(原子核)四周。只有原子中存在唯一电子时,原子轨域才能精准符合「大气」的形状。当原子中有越来越多电子时,电子越倾向均匀分布在原子核四周的空间体积中,因此「电子云」越倾向分布在特定球形区域内(区域内电子出现机率较高)。

Atomic orbital 原子轨道(重定向自Electron cloud)
![]() ![]() ![]() An atomic orbital is a mathematical function that describes the wave-like behavior of either one electron or a pair of electrons in an atom. This function can be used to calculate the probability of finding any electron of an atom in any specific region around the atom's nucleus. The term, atomic orbital, may also refer to the physical region or space where the electron can be calculated to be present, as defined by the particular mathematical form of the orbital. |
