These are all isoelectronic, they all have the same electron configuration. And we can also think about going back to atomic size for a second.
这些都是等电子的，它们都有相同的电子排布，而,我们还可以再回想一下原子尺寸的概念。

The researchers analysed the sizes and structures of ash particles using a variety of techniques, such as atomic force microscopy, scanning electron microscopy and X-ray diffraction.
研究人员使用不同的技术研究了火山灰颗粒的尺寸和结构，例如原子力显微镜、电子扫描显微镜和X射线衍射。

We'll then take a turn to talking about the periodic table, we'll look at a bunch of periodic trends, including ionization energy, electron affinity, electronegativity and atomic radius.
