1·The affection on the enthalpies of formation aroused by factors, such as size factor, electronegativity, the energy of orbit of selectron etc, is also discussed.
还讨论了尺寸因子，电负性，选择子的轨道能量等因素对形成焓的影响。
2·So, in contrast, if it has a low electronegativity, this then is going to be an electron donor.
那么，相反地，如果它的电负性很低，它将会是一个电子的施主。
3·And so, this is a schematic of the electronegativity scale.
因此，这是电负性大小的示意图。
4·All right, so it's very common to talk about electronegativity of different atoms, and you can look up tables of these.
好，这是很常见的，对于不同原子电负性的讨论，大家可以查阅这方面的表格。
5·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.
然后我们再开始讲元素周期表，我们会看到很多周期性规律，比如电离能，电子亲和能，电负性以及原子半径。
